We run xymon servers the old-school way*: local config of clients with client-side evaluation of thresholds. I run a mashup of ancient BB, newer BBPE, and even newer xymon clients.
I'm in need of memory monitoring on a CentOS 7 host. The client I have there (I think it is a BBPE version) doesn't provide it. So I reached back and grabbed a bb-memory.sh from some other system. But it doesn't work cleanly :(
For linux, the script captures the output of 'free -m' and then populates variables:
FREE_PHYS
FREE_ACT
FREE_SWAP
by grepping lines from the result:
Mem
• Swap
and my version of 'free' (3.3.10) has moved the '+/-' information up into a new column in the 'Mem' line. I don't see a way to adjust the 'free' command to return results in the old format, so I'll need to accommodate the new format in the shell script.
Before I go dive in and engineer my own parser, I thought I'd ask here:
Does anyone have a bb-memory.sh they'd share with me?
Alternatively, I could remove the old client and install something newer. But the last time I tried compiling the client with the 'local-config' option, it didn't work out well. So my second question is:
Is there a linux client package that correctly support local-config?
* Yeah, I know there are plenty who think this is a terrible idea and can't stand the concept. But I don't own most of the hosts. So I don't want to have them dragging my central code down to them. Nor do I know the business rules which define success or failure. It's up to the owner of the host to set those things.
