Floppy being polled

[rony]

Yah, don't use Microsoft SNMP.....

Sorry, there is not a better answer.

[Beaujolais]

What SNMP agent would you recommend? Preferably free.

[TheWitness]

Net-SNMP. The Microsoft version is very very bad about polling drives.

OK, thanks.

I've installed NET-SNMP but I can't figure out how to enable UCD-SNMP and HOST-RESOURCES data.
Only RFC1213 standard mib is responding, nothing else.

I've red all the availabile win32 related documentation but no luck.

Anybody can share snmpd.conf working example for windows please?

thx

If you already have to install software on your MS boxes you could use SNMP-Informant (http://www.snmp-informant.com/). The free version offers OIDs for memory, processor, logical disk, network interface.

Thanks

If anyone is interested, I have done a few things that have resolved this on my end, I also added a few extra things that are useful to me, maybe not so useful to others.

I modified "host_disk.xml" to add an Input for the "Total Size". I do this so cacti will now cache this. It rarely if ever changes, so I would rather not have to repull it from servers every polling. This saves me about 30 seconds each polling with the 80 win servers I poll. I also added an Output called "Percent", which I will explain later.

In "ss_host_disk.php" I modified the 'total' query to first check and see if we are already caching the total, and if so, then use it, otherwise walk it as normal. Then I have added the extra output for 'percent'. I re-get the 'used' (to be sure its accurate) and pull the total from the cache and one simple math function later I have a "% Used Space" which is outputted as a datasource (I'll explain why in a sec). Next I also happen to rewalk the "total" when I do the query so that I can leave out anything that doesn't have a toal size of over 100000 bytes, which means it leaves out the floppy, cd-rom, and the virtual memory from the "Create Graphs" screen, so a simple "Check All" does all the hard drives, without having to bother unchecking these misc devices. The floppy can't be polled if you can't create a graph for it.

I perfer a datasource instead of a CDEF for the Percent since I want to be able to set a Threshold on the Percent, instead of just using it to show it on the graph. I am sure there is a better way to do a few of these things, but this was easy enough for me. Let me know if there is anything you see a better way to do, or if you happen to like the changes I made.

I wrote graph templates for Windows XP/2K/2K3 memory and disk counters that don't poll the floppy drive. They are based on the free, rock-solid SNMP Informant.
I'm thinking of contributing this as a new host template, using some native Microsoft counters and some SNMP Informant counters. Anyone interested? Regards,

Georger

Is there any solution to this a:\ problem yet?
