Snmpget.exe processes eating up the CPU

[dig3doo]

Hi,

I have successfully installed Cacti on a 3.2Ghz 1GB memory server. I am currently monitoring 2 Catalyst 6500 and a couple of 3745’s. The graphing is great except the server is taking a bit of strain. A couple of snmpget.exe processes are eating up the processor, it constantly sits at 100%.

Is this normal? Any suggestions?

I am running Cacti with:
Windows 2003
Cacti-0.8.6c
Mysql-4.0.23
Activepearl-5.8.3.809
Apache-2.0.52
Php-5.0.3
Rrdtool-1.0.48.win32
Net-snmp-5.2-1

Thanks

Cacti rules
Any future plans for netflow support?

Use Cactid instead of cmd.php when you are using snmpv2 to poll hosts. It is not integrated into PHP yet. We are working with the developers on integration so as to speed up cmd.php. But as of yet, no luck.

Thanks for the reply,

I manage quite a large network (7000hosts, 150 routers), what are the limitations of cacti on a windows platform? I have noticed that the max values of the graphs don’t accurately represent the interface (if the link is 512k the graph sometimes indicates 600+) is this a problem with my installation? How do I get the interface descriptions onto the graph?

Still think Cacti rules.

Could be interface resets. Cacti, although great (and I help develop) currently lacks a builtin spike killer that adjusts for interface resets. Also, depending on direction, it could be indicative of a buffer overrun caused by unthrottled traffic such as UDP traffic. The correct answer of course depends on a lot of additional informaiton being provided.

Is there any way of getting Cacti to read the interface speed and limit the graph height to that speed?

Thanks.

Still cant get the interface descriptions onto the graphs

Sure, there is the maximum graph height in the graph settings and max value for the RRD file (Data Source).
