+Analyze
+=======
+
+
+The analyze command is a front-end to various tools that let us analyze
+package installations. Each analyzer is a module for a different kind
+of analysis that can be done on a package installation, including (but not
+limited to) binary, log, or text analysis. Thus, the analyze command group
+allows you to take an existing package install, choose an analyzer,
+and extract some output for the package using it.
+
+
+-----------------
+Analyzer Metadata
+-----------------
+
+For all analyzers, we write to an ``analyzers`` folder in ``~/.spack``, or the
+value that you specify in your spack config at ``config:analyzers_dir``. 
+For example, here we see the results of running an analysis on zlib:
+
+.. code-block:: console
+
+    $ tree ~/.spack/analyzers/
+    └── linux-ubuntu20.04-skylake
+        └── gcc-9.3.0
+            └── zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2
+                ├── environment_variables
+                │   └── spack-analyzer-environment-variables.json
+                ├── install_files
+                │   └── spack-analyzer-install-files.json
+                └── libabigail
+                    └── spack-analyzer-libabigail-libz.so.1.2.11.xml
+    
+
+This means that you can always find analyzer output in this folder, and it
+is organized with the same logic as the package install it was run for. 
+If you want to customize this top level folder, simply provide the ``--path``
+argument to ``spack analyze run``. The nested organization will be maintained
+within your custom root.
+
+-----------------
+Listing Analyzers
+-----------------
+
+If you aren't familiar with Spack's analyzers, you can quickly list those that 
+are available:
+
+.. code-block:: console
+
+    $ spack analyze list-analyzers
+    install_files            : install file listing read from install_manifest.json
+    environment_variables    : environment variables parsed from spack-build-env.txt
+    config_args              : config args loaded from spack-configure-args.txt
+    libabigail               : Application Binary Interface (ABI) features for objects
+
+
+In the above, the first three are fairly simple - parsing metadata files from
+a package install directory to save
+
+-------------------
+Analyzing a Package
+-------------------
+
+The analyze command, akin to install, will accept a package spec to perform
+an analysis for. The package must be installed. Let's walk through an example
+with zlib. We first ask to analyze it. However, since we have more than one
+install, we are asked to disambiguate:
+
+.. code-block:: console
+
+    $ spack analyze run zlib
+    ==> Error: zlib matches multiple packages.
+      Matching packages:
+        fz2bs56 zlib@1.2.11%gcc@7.5.0 arch=linux-ubuntu18.04-skylake
+        sl7m27m zlib@1.2.11%gcc@9.3.0 arch=linux-ubuntu20.04-skylake
+      Use a more specific spec.
+
+
+We can then specify the spec version that we want to analyze:
+
+.. code-block:: console
+
+    $ spack analyze run zlib/fz2bs56
+
+If you don't provide any specific analyzer names, by default all analyzers 
+(shown in the ``list-analyzers`` subcommand list) will be run. If an analyzer does not
+have any result, it will be skipped. For example, here is a result running for
+zlib:
+
+.. code-block:: console
+
+    $ ls ~/.spack/analyzers/linux-ubuntu20.04-skylake/gcc-9.3.0/zlib-1.2.11-sl7m27mzkbejtkrajigj3a3m37ygv4u2/
+    spack-analyzer-environment-variables.json
+    spack-analyzer-install-files.json
+    spack-analyzer-libabigail-libz.so.1.2.11.xml
+
+If you want to run a specific analyzer, ask for it with `--analyzer`. Here we run
+spack analyze on libabigail (already installed) _using_ libabigail1
+
+.. code-block:: console
+
+    $ spack analyze run --analyzer abigail libabigail
+
+
+.. _analyze_monitoring:
+
+----------------------
+Monitoring An Analysis
+----------------------
+
+For any kind of analysis, you can
+use a `spack monitor <https://github.com/spack/spack-monitor>`_ "Spackmon"
+as a server to upload the same run metadata to. You can
+follow the instructions in the `spack monitor documentation <https://spack-monitor.readthedocs.org>`_
+to first create a server along with a username and token for yourself.
+You can then use this guide to interact with the server.
+
+You should first export our spack monitor token and username to the environment:
+
+.. code-block:: console
+ 
+    $ export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+    $ export SPACKMON_USER=spacky
+
+
+By default, the host for your server is expected to be at ``http://127.0.0.1``
+with a prefix of ``ms1``, and if this is the case, you can simply add the
+``--monitor`` flag to the install command:
+
+.. code-block:: console
+
+    $ spack analyze run --monitor wget
+
+If you need to customize the host or the prefix, you can do that as well:
+
+.. code-block:: console
+
+    $ spack analyze run --monitor --monitor-prefix monitor --monitor-host https://monitor-service.io wget
+
+If your server doesn't have authentication, you can skip it:
+
+.. code-block:: console
+
+    $ spack analyze run --monitor --monitor-disable-auth wget
+    
+Regardless of your choice, when you run analyze on an installed package (whether
+it was installed with ``--monitor`` or not, you'll see the results generating as they did
+before, and a message that the monitor server was pinged:
+
+.. code-block:: console
+
+    $ spack analyze --monitor wget
+    ...
+    ==> Sending result for wget bin/wget to monitor.

+--------------------------
+Creating build cache files
+--------------------------
 
-.. note::
-
-    We use the terms "build cache" and "mirror" often interchangeably. Mirrors
-    are used during installation both for sources and prebuilt packages. Build
-    caches refer to mirrors that provide prebuilt packages.
-
-
-----------------------
-Creating a build cache
-----------------------
+A compressed tarball of an installed package is created. Tarballs are created
+for all of its link and run dependency packages as well. Compressed tarballs are
+signed with gpg and signature and tarball and put in a ``.spack`` file. Optionally,
+the rpaths (and ids and deps on macOS) can be changed to paths relative to
+the Spack install tree before the tarball is created.
 
 Build caches are created via:
 
 .. code-block:: console
 
-    $ spack buildcache create <path/url/mirror name> <spec>
+    $ spack buildcache create <spec>
 
-This command takes the locally installed spec and its dependencies, and
-creates tarballs of their install prefixes. It also generates metadata files,
-signed with GPG. These tarballs and metadata files are then pushed to the
-provided binary cache, which can be a local directory or a remote URL.
 
-Here is an example where a build cache is created in a local directory named
-"spack-cache", to which we push the "ninja" spec:
+If you wanted to create a build cache in a local directory, you would provide
+the ``-d`` argument to target that directory, again also specifying the spec.
+Here is an example creating a local directory, "spack-cache" and creating
+build cache files for the "ninja" spec:
 
 .. code-block:: console
 
-    $ spack buildcache create --allow-root ./spack-cache ninja
-    ==> Pushing binary packages to file:///home/spackuser/spack/spack-cache/build_cache

+    gpg: using "E6DF6A8BD43208E4D6F392F23777740B7DBD643D" as default secret key for signing
 
-Not that ``ninja`` must be installed locally for this to work.
+Note that the targeted spec must already be installed. Once you have a build cache,
+you can add it as a mirror, discussed next.
 
-We're using the ``--allow-root`` flag to tell Spack that is OK when any of
-the binaries we're pushing contain references to the local Spack install
-directory.

+==========
+Monitoring
+==========
+
+You can use a `spack monitor <https://github.com/spack/spack-monitor>`_ "Spackmon"
+server to store a database of your packages, builds, and associated metadata 
+for provenance, research, or some other kind of development. You should
+follow the instructions in the `spack monitor documentation <https://spack-monitor.readthedocs.org>`_
+to first create a server along with a username and token for yourself.
+You can then use this guide to interact with the server.
+
+-------------------
+Analysis Monitoring
+-------------------
+
+To read about how to monitor an analysis (meaning you want to send analysis results
+to a server) see :ref:`analyze_monitoring`.
+
+---------------------
+Monitoring An Install
+---------------------
+
+Since an install is typically when you build packages, we logically want
+to tell spack to monitor during this step. Let's start with an example
+where we want to monitor the install of hdf5. Unless you have disabled authentication
+for the server, we first want to export our spack monitor token and username to the environment:
+
+.. code-block:: console
+ 
+    $ export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+    $ export SPACKMON_USER=spacky
+
+
+By default, the host for your server is expected to be at ``http://127.0.0.1``
+with a prefix of ``ms1``, and if this is the case, you can simply add the
+``--monitor`` flag to the install command:
+
+.. code-block:: console
+
+    $ spack install --monitor hdf5
+
+
+If you need to customize the host or the prefix, you can do that as well:
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-prefix monitor --monitor-host https://monitor-service.io hdf5
+
+
+As a precaution, we cut out early in the spack client if you have not provided
+authentication credentials. For example, if you run the command above without
+exporting your username or token, you'll see:
+
+.. code-block:: console
+
+    ==> Error: You are required to export SPACKMON_TOKEN and SPACKMON_USER
+
+This extra check is to ensure that we don't start any builds,
+and then discover that you forgot to export your token. However, if 
+your monitoring server has authentication disabled, you can tell this to
+the client to skip this step:
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-disable-auth hdf5
+
+If the service is not running, you'll cleanly exit early - the install will
+not continue if you've asked it to monitor and there is no service.
+For example, here is what you'll see if the monitoring service is not running:
+
+.. code-block:: console
+
+    [Errno 111] Connection refused
+
+
+If you want to continue builds (and stop monitoring) you can set the ``--monitor-keep-going``
+flag. 
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-keep-going hdf5
+
+This could mean that if a request fails, you only have partial or no data
+added to your monitoring database. This setting will not be applied to the
+first request to check if the server is running, but to subsequent requests.
+If you don't have a monitor server running and you want to build, simply
+don't provide the ``--monitor`` flag! Finally, if you want to provide one or
+more tags to your build, you can do:
+
+.. code-block:: console
+
+    # Add one tag, "pizza"
+    $ spack install --monitor --monitor-tags pizza hdf5
+
+    # Add two tags, "pizza" and "pasta"
+    $ spack install --monitor --monitor-tags pizza,pasta hdf5
+
+
+----------------------------
+Monitoring with Containerize
+----------------------------
+
+The same argument group is available to add to a containerize command. 
+
+^^^^^^
+Docker
+^^^^^^
+
+To add monitoring to a Docker container recipe generation using the defaults,
+and assuming a monitor server running on localhost, you would
+start with a spack.yaml in your present working directory:
+
+.. code-block:: yaml
+
+   spack:
+     specs:
+       - samtools
+
+And then do:
+
+.. code-block:: console
+
+    # preview first
+    spack containerize --monitor
+    
+    # and then write to a Dockerfile
+    spack containerize --monitor > Dockerfile
+    
+    
+The install command will be edited to include commands for enabling monitoring.
+However, getting secrets into the container for your monitor server is something
+that should be done carefully. Specifically you should:
+
+ - Never try to define secrets as ENV, ARG, or using ``--build-arg``
+ - Do not try to get the secret into the container via a "temporary" file that you remove (it in fact will still exist in a layer)
+
+Instead, it's recommended to use buildkit `as explained here <https://pythonspeed.com/articles/docker-build-secrets/>`_.
+You'll need to again export environment variables for your spack monitor server:
+
+.. code-block:: console
+
+    $ export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+    $ export SPACKMON_USER=spacky
+
+And then use buildkit along with your build and identifying the name of the secret:
+
+.. code-block:: console
+
+    $ DOCKER_BUILDKIT=1 docker build --secret id=st,env=SPACKMON_TOKEN --secret id=su,env=SPACKMON_USER -t spack/container . 
+    
+The secrets are expected to come from your environment, and then will be temporarily mounted and available
+at ``/run/secrets/<name>``. If you forget to supply them (and authentication is required) the build
+will fail. If you need to build on your host (and interact with a spack monitor at localhost) you'll
+need to tell Docker to use the host network:
+
+.. code-block:: console
+
+    $ DOCKER_BUILDKIT=1 docker build --network="host" --secret id=st,env=SPACKMON_TOKEN --secret id=su,env=SPACKMON_USER -t spack/container . 
+    
+
+^^^^^^^^^^^
+Singularity
+^^^^^^^^^^^
+
+To add monitoring to a Singularity container build, the spack.yaml needs to
+be modified slightly to specify wanting a different format:
+
+
+.. code-block:: yaml
+
+   spack:
+     specs:
+       - samtools
+     container:
+       format: singularity
+       
+       
+Again, generate the recipe:
+
+
+.. code-block:: console
+
+    # preview first
+    $ spack containerize --monitor
+    
+    # then write to a Singularity recipe
+    $ spack containerize --monitor > Singularity
+
+
+Singularity doesn't have a direct way to define secrets at build time, so we have
+to do a bit of a manual command to add a file, source secrets in it, and remove it.
+Since Singularity doesn't have layers like Docker, deleting a file will truly
+remove it from the container and history. So let's say we have this file,
+``secrets.sh``:
+
+.. code-block:: console
+
+    # secrets.sh
+    export SPACKMON_USER=spack
+    export SPACKMON_TOKEN=50445263afd8f67e59bd79bff597836ee6c05438
+
+
+We would then generate the Singularity recipe, and add a files section,
+a source of that file at the start of ``%post``, and **importantly**
+a removal of the final at the end of that same section.
+
+.. code-block::
+
+    Bootstrap: docker
+    From: spack/ubuntu-bionic:latest
+    Stage: build
+
+    %files
+      secrets.sh /opt/secrets.sh 
+
+    %post
+      . /opt/secrets.sh
+
+      # spack install commands are here
+      ...
+      
+      # Don't forget to remove here!
+      rm /opt/secrets.sh
+
+
+You can then build the container as your normally would.
+
+.. code-block:: console
+
+    $ sudo singularity build container.sif Singularity 
+
+
+------------------
+Monitoring Offline
+------------------
+
+In the case that you want to save monitor results to your filesystem
+and then upload them later (perhaps you are in an environment where you don't
+have credentials or it isn't safe to use them) you can use the ``--monitor-save-local``
+flag.
+
+.. code-block:: console
+
+    $ spack install --monitor --monitor-save-local hdf5 
+
+This will save results in a subfolder, "monitor" in your designated spack
+reports folder, which defaults to ``$HOME/.spack/reports/monitor``. When
+you are ready to upload them to a spack monitor server:
+
+
+.. code-block:: console
+
+    $ spack monitor upload ~/.spack/reports/monitor 
+
+
+You can choose the root directory of results as shown above, or a specific
+subdirectory. The command accepts other arguments to specify configuration
+for the monitor.

-
-^^^^^^^^^^^^^^^^^^^^^^^^
-``disinherit``
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-When you inherit from a package in Spack, you inherit all the metadata from its
-directives, including ``version``, ``provides``, ``depends_on``, ``conflicts``, etc. For
-example, ``NewPackage`` above will have four versions: ``1.0`` and ``2.0`` inherited
-from ``MyPackage``, as well as, ``3.0``, and ``4.0`` defined in ``NewPackage``.
-
-If you do not want your package to define all the same things as its base class, you can
-use the ``disinherit`` directive to start fresh in your subclass:
-
-.. code-block:: python
-
-   from spack.pkg.myrepo.my_package import MyPackage
-
-   class NewerPackage(MyPackage):
-       disinherit("versions")    # don't inherit any versions from MyPackage
-       version("5.0", "08721a102fefcea2ae4add8c9cc548df77e9224f5385ad0872a9150fdd26a415")
