I have added a tree of MIBs (in the ‘experimental’ section of the tree) for my own application services to respond to snmp requests. This is for determining the health of a running service.
I can view the objects using snmpwalk, and I can add the host running the agent to observium. I can see all the information retrieved from the ‘well-known’ MIBs (uptime, load, etc.) in observium for my extended agent, but I can’t see any of my own MIBs.
Where do I look for how to let observium know about my MIBs so that it can show the data in a tabular or graphical format? I see the includes/polling/unix-agent/* as some examples, but it’s not clear to me where the mapping between my OIDs goes to the variables inside of running observium, so I can invoke rrdtool_create properly. It’s also not clear to me how I layout the various graphs on the page, once I have them created. If there is some documentation for that somewhere, or a particularly good example in the code to look at which would make it clear, that would be great.
Thanks
