For now this still have to be enabled with a config like this in a .conf
file in srv/telegraf/extra-config/  :

    [[inputs.execd]]
      name_override = "slapos"
      # this needs sudo when using can not access supervisor socket, like when being installed in root slapos
      command = ["/usr/bin/sudo", "$SOFTWARE_DIR/go.work/bin/telegraf-input-slapos", "-config", "/path/to/slapos.conf"]

/path/to/slapos.conf would contain something like this:

    [[inputs.slapos]]
      ## Folder where partitions are located
      instance_root = "/srv/slapgrid/"

      ## filepath.Glob pattern to look for recursive instances
      recursive_instance_glob_pattern = "*/srv/runner/inst*/"

      ## Path of supervisor socket, relative to instance root
      socket_name = "sv.sock"

This version has a new sql input, that can be used to get metrics from sql
queries.

To run the benchmark locally:

 - Install software/slapos-sr-testing and create an instance
 - Source the shell script published by the instance to setup
   environment variables
 - execute `python_for_test -m unittest -v  test.benchmarks`

This promise was generally used to check the connection quality to the
backend with ICMP, by using ping. This is currently obsoleted by health-check
and other parameters in that group.

The parameter to setup the promise is provided by shared instance requester,
that person has no access to those results, as shared instances can't be
monitored directly, all results are only available to the cluster operator in
contrast to health-check, which results are logged to backend_log, to which
shared instance requester has access.

1) stack/erp5/zope-versions.cfg
2) stack/slapos.cfg
3) component/ZODB/buildout.cfg.

and remove stack/erp5/ztk-versions.cfg as we need only small part of it.

stack/slapos.cfg should be listed in the begining of software release extends list.

software-dev.cfg will use most recent version of OSIE coupler code.
