Enterprise inventorying of hosts that have overlapping cf-agent runs

[Aleksey Tsalolikhin]

Does anybody have policy they'd like to share of inventorying hosts that have overlapping cf-agent runs?

You mean the number of running cf-agent process?

I want to set a class if there is more than one cf-agent process.  I don't care how many there are as I have policy to kill cf-agent processes to prevent process pile-ups, so the number no longer gets high, but I still want to know where cf-agent processes overlap as it could indicate trouble.  And now due to my clean-up policy, if pile-ups are chronic, cf-agents won't finish their runs, like ever...

Hi Aleksey,

See attachments

- inventory count of cf-agent processes based on regex against
/var/cfengine/state/cf_procs
- measure count for graphing and anomonly detection
- Classes defined if there are more than 1 running agent
(as detected by cf-monitord, perhaps this ought to just
use the same probe instead of relying on the potentially
older mon data)
- have_multiple_concurrent_cf_agent_processes
- have_x_concurrent_cf_agent_processes
