Description
Extend the admin tool to collect statistics from the DB and the backend.
Allow for pluggable presentation layers.
More specifically:
a) Collect DB statistics: number of users, number of VMs, number of invitations, number of images, distribution of VMs per image, etc. Access the DB directly, over Django.
b) Collect backend statistics: If possible, over RAPI: number of VMs, Ganeti queue length, number of nodes, total disk GB, used/free disk GB, total memory, used/free memory.
Presentation layers. Initially:
a) simple text presentation, e.g. snf-admin stats, using a nice tabular text display.
b) output in a specific plugin format, initially munin, e.g. with a --output munin, --output collectd option.
This way the tool will be callable as a plugin. Its data will be fed to a munin or collectd infrastructure for presentation.

Where can I find documentation for the required output formats?

Please see here for info on how to write a munin plugin:

I think it is a better idea to be munin (and collected) agnostic and have other scripts that will handle the format conversion.
For example, a munin plugin needs to accept a config argument that will output graph configuration. Moreover it may decide to only create graphs for a subset of the output. Since parsing stats output is fairly easy, keeping all this logic external is far more flexible.
As an example, a munin plugin to graph the number of VMs would be:
#!/bin/bash
if [ "$1" = "config" ]; then
echo "graph_title Number of VMs"
echo "graph_vlabel VMs"
exit 0
fi
echo -n "vms.value"
snf-admin stats | grep VMs | cut -d: -f2

#6 Updated by Vangelis Koukis over 11 years ago
- Target version changed from v0.6.1 to v0.6.2
#7 Updated by Vangelis Koukis over 11 years ago
- Target version changed from v0.6.2 to 67
#8 Updated by Vangelis Koukis over 11 years ago
- Status changed from New to Assigned
- Target version changed from 67 to v0.8.0
Moving to v0.8, this needs to be re-evaluated in the context of the new web-based admin interface.
#9 Updated by Vangelis Koukis over 11 years ago
- Due date set to 11/11/2011
#10 Updated by Vangelis Koukis about 11 years ago
- Target version changed from v0.8.0 to v0.9.0
Again moving to v0.9, again needs to be seen as part of the web-based admin interface.
