[solved] Lots of BOOST: Poller[0] PROGERR: ERRNO:'2'

[ksj]

Getting these errors for every rrd written. Disk I/O is currently horrible. Boost version is 4.2. Permissions are fine as the rrd does get written. Any ideas?

08/28/2010 11:10:58 AM - BOOST: Poller[0] PROGERR: ERRNO:'2' TYPE:'Warning' MESSAGE:'pclose(): supplied argument is not a valid stream resource' IN FILE:'E:\inetpub\wwwroot\cacti\plugins\boost\setup.php' LINE NO:'1633'

08/28/2010 11:10:58 AM - BOOST: Poller[0] PROGERR: ERRNO:'8' TYPE:'Notice' MESSAGE:'Undefined variable: fp' IN FILE:'E:\inetpub\wwwroot\cacti\plugins\boost\setup.php' LINE NO:'1633'

Win2008r2 IIS 7.5, Cacti 0.8.7e, Win32 rrdtool 1.2.30, php 5.2.14, mysql 5.0.88, Spine 0.8.7e, cygwin 1.7.6, PIA 2.5

TIA

Whats you system size and poller interval. Show some stats from your log.

Polling is every 5 minutes. Boost configured to run every 2 hours or 2M records. Boost gets 3G, PHP is set for 2G, and Direct population of poller_output_boost is enabled.

The system has 500Gb of storage using 10K rpm disks, 16G of RAM and 4 processor cores.

As I say, disk IO is super slow so I'm not surprised at the time it took to write the updates. There are no errors in the log and the only warnings are about recache events for a couple devices.

Code: Select all

du -hs rra

Please. The rrdupdates are too slow.

Thanks

e:\inetpub\wwwroot\cacti> du -hs rra

167G rra

You should get off windows. Although those rrd's are pretty big. The other solution is to go to a PCIe based SSD.

Always check everything 3 times. In my case 4 or more is necessary I guess . This is more like what I was expecting:

This host is a HyperV VM btw. Newer versions of Windows aren't all that bad wrt performance IMO...

I'm seeing this error too on a much smaller set of RRAs. Anything I can do about this? Not clear if it actually affects anything. I have this for total RRA space:

# du -hs rra
2.4G rra

My stats look like this:
