I am new to this whole network monitoring lark but have just installed zenoss 2.0.6 because I want to get a near real time (say 5 seconds latency) graphical representation of some statistics coming from a custom MIB over a network.
I have my MIB working fine, I can poll it using snmpwalk and it returns good values. I have imported my MIB into zenoss which sees all the OIDs and names just fine, I have created data types and data points in the template for one of my end nodes running the MIB daemon, I have created 5 graphs to show 5 different data types. The first two ran ok for about half and hour, then stopped. The next two have never shown any data, the last one runs fine. I queried the RRD database which shows 'nan's for all the values which don't show on the graph so I can't fault the graph itself, it appears RRD is not getting the right values. But if I query snmpwalk using an OID copy/pasted from zenoss it works fine. Why would this be going wrong for 4 out of 5 graphs? On a maybe related note, for the first couple of days of running this, the graphs (I'm on the default CPU utilization etc graphs now) would sometimes cut out. The only way I found to start them again was run #/etc/init.d/zenoss restart . Again the RRD Database would be full of 'nan's in those blank periods. Is this likely related? On a different note, I want to change the update rate to about 5 seconds. I changed the 'SNMP Performance Cycle Interval' value for the localhost to 5 seconds, pressed save and restarted zenoss for good measure and nothing happened. I changed all the other values on that page to 5 seconds too and, not suprisingly, nothing happened. I had a quick look at the code and, although I don't know any Python, it appears to me that it sets a variable perfsnmpCycleInterval to '5 * 60' by default so I assume it is not managing to set the variable to my value. Any ideas why not? Thanks for any help. I have had much more success than I had with OpenNMS but I am just not quite where I need to be yet.
