[solved] Physical memory graph stop working

[petoulachi]

Hello,

I'm using cacti 0.8.7g without issue with my windows 2008R2 servers.
For one server, the memory use graph just stop working. No data are display, nor the total memory and used memory.

I've try to remove and readd the graph without success. Also tried to remove the graph AND associated data, but no more luck.

I don't have any idea to see what's wrong here. Others graph on the server work well (hard drives, CPU, network, fans etcetc).

Thanks for your help !

Ok, so :
-cacti is installed on a windows2008R2 server, using the latest windows installer and IIS
-servers that are monitored are all windows2008R2

RDDTools says "OK" for the graph. Here is the command :

Code: Select all

RRDTool Command:

GPRINT:b:LAST:" Current\:%8.2lf %s"  \
GPRINT:b:AVERAGE:"Average\:%8.2lf %s"  \
GPRINT:b:MAX:"Maximum\:%8.2lf %s\n" 

But in the poller log, I have a warning every five minutes : SNMP Timeout for two OID ( .1.3.6.1.2.1.25.2.3.1.6.7) on this server. I Suspect that this two OID are total RAM and used RAM, but how do I check that ? And more important, what can I do to solve this ?

Regards,

Use net-snmp snmpwalk to check if that OID is valid and post the results

Code: Select all

snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.25.2.3.1

[petoulachi]

Seems unrelated :

C:\Users\root>snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.25.2.3.1
Cannot find module (MIB-Dell-10892): At line 1 in (none)
Timeout: No Response from localhost

I thinks it's some tests I've made to monitor temperature ?

[BSOD2600]

That output means your local pc does not respond to snmp requests... which is bad if you're tying to get cacti to graph data from it. double-check your snmp agent configuration.

[petoulachi]

My god I'm such a noob sometimes...

Okay so :
running this on the cacti server :

Code: Select all

C:\Users\root>snmpwalk -v 1 -c mydomain localhost .1.3.6.1.2.1.25.2.3.1.6.7
Cannot find module (MIB-Dell-10892): At line 1 in (none)
HOST-RESOURCES-MIB::hrStorageUsed.7 = INTEGER: 40805
C:\Users\root>

now, running it from the cacti server to the server with RAM graph issue :

Code: Select all

C:\Users\root>snmpwalk -v 1 -c mydomain server.mydomain.com .1.3.6.1.2.1.25.2.3.1.6.7
Cannot find module (MIB-Dell-10892): At line 1 in (none)
C:\Users\root>

So it does not give any result ? But some other graph (disk utilization, network, CPU...) work fine on this server.

Also, how do I can know the OID for the RAM graph ?

[BSOD2600]

1) the MIB-Dell-10892 problem really isn't that important.
2) You didnt snmpwalk the OID I specified. this will show you all storage devices.

Windows re-assigned the OIDs for the memory on your system. Notice how initially it was .1.3.6.1.2.1.25.2.3.1.6.7 and now from the snmpwalk you can see its .1.3.6.1.2.1.25.2.3.1.6.6?

Click the green circle next to the associated data query for that devices. Otherwise, you can schedule reindexing to occur with /cacti/cli/ scripts.

[petoulachi]

I've run a reindex and the RAM graph is now working again.

Thanks a lot for your help. btw why the fuck do Windows changes OID ??

[BSOD2600]

Typically they'll change when a new disk device is added (usb, external, etc). They can also change when certain windows updates are installed and/or system is rebooted.
