I've started having problems with Inventory since moving to 7.3 and I'm trying to figure out how to diagnose what the problem might be, but I'm not seeing anything in the web interface that might help me diagnose what the problem might be. Since we upgraded to 7.3 we've also started managing a bunch more items too, so I'm not sure if its because of the upgrade or maybe specific items causing it to hang up.
I could have sworn we were at over 90% of the devices inventoried and then next time I looked it went down to about 7% and the job was running for a couple days. Rather than have a job that just inventories everything, I decided to change it so it only does Cisco items that have never been inventoried before (ie: devices that have a last inventoried date of 12/30/1899). When I "View selected nodes" in the "Choose Nodes" step of the job creation it appears to be selecting a bunch of nodes, so I know a bunch should be left to be done. Not to mention its telling me I have something like 48% of nodes inventoried right now out of about 1500 nodes. At first I would run the job for awhile, it would inventory maybe 5-10% of the nodes and then appear to hang. So after letting it run awhile I would stop the job and then restart it a short time later and it would do another 5-10% of them. However, now its stuck at 48% no matter how often I try and run the job. I've tried adjusting the # of nodes being inventoried both up and down. I've even gone in and removed a few things from being inventoried, mostly stuff that shouldn't apply like Juniper, Brocade and server related stuff. I've also removed the "Bridge MIB" since I've heard doing the Layer-2 stuff could bog it down.
Not sure of where to look to try and figure out why it seems to be hanging up, any suggestions?
