Is the clock on your server accurate? I'm just wondering if the server is missing time ticks and speeding up the clock.

I am still getting 'gaps' in my graphs, I assume that are caused by zenperfsnmp timeouts and retries. I have cleaned out as many problem areas as I could think of such as: 1. Moved to an external MySQL source to reduce load 2. Stopped monitoring WMI event logs (actually all WMI) on windows servers 3. Added HRSWInstalledMap to my zProperties exceptions for my linux servers 4. Made sure any out of production servers were marked as in Maintenance mode This has dramatically improved the overall performance, but I am still getting gaps. Searching through my zenperfsnmp.log I find: 2007-01-18 11:09:18 INFO zen.zenperfsnmp: collected 166 of 166 devices in 18.17 2007-01-18 11:09:59 INFO zen.zenperfsnmp: Unresponsive devices: [['SERVER1', 1, 1721], ['10.10.10.100', 1, 1724]] 2007-01-18 11:10:17 INFO zen.zenperfsnmp: collected 166 of 166 devices in 17.97 2007-01-18 11:10:59 INFO zen.zenperfsnmp: Unresponsive devices: [['SERVER1', 1, 1721], ['10.10.10.100', 1, 1724]] 2007-01-18 11:11:16 INFO zen.zenperfsnmp: collected 166 of 166 devices in 16.52 2007-01-18 11:18:18 INFO zen.zenperfsnmp: Configured 166 devices 2007-01-18 11:18:18 INFO zen.zenperfsnmp: Unresponsive devices: [['SERVER1', 1, 1721], ['10.10.10.100', 1, 1725]] 2007-01-18 11:18:44 INFO zen.zenperfsnmp: collected 166 of 166 devices in 26.24 2007-01-18 11:19:18 INFO zen.zenperfsnmp: Unresponsive devices: [['SERVER1', 1, 1721], ['10.10.10.100', 1, 1725]] The log timestamps jump 7 minutes between one poll and the next, which causes the gap. I can't see any errors at that time period so I can't figure out why there is a gap? Anyone willing to sell me a vowel?
