Can you describe your situation a little better? What is not working, exactly?

Hi EnigmA-X
My requirement is if the maximum disk space reached to 98.5% for 15 Mins then i need a trigger . As you provided me the trigger description i tried with that , for testing purpose i gave the low threshold and tried then i got alert but the alert is not showing in the form of percentage .For reference please find the trigger details . Please hel me out

Disk Space on / for Citi ATL616 Reached the 98.5% for 15 min: PROBLEM

Status: PROBLEM
Host: toko dub616
Severity: High

Last Item Value:
122.89 GBytes (I want these to be in %)




{toko dub616:hrStorageUsed.31.last(900)}*100/{Citi dub616:hrStorageSize.31.last(0)}>95

What exactly do you mean "unable to get the oids"? Do you get anything?
You should be able to snmpwalk hrStorage.

Also, you must have snmp installed and running on your SLES server.

Hi Mrken,
I want to monitor the total CPU Utilization for linux server through SNMP , Can you please help me how to do that , Please tell me which oid i need to select

CPU
percentage of user CPU time: .1.3.6.1.4.1.2021.11.9.0
raw user cpu time: .1.3.6.1.4.1.2021.11.50.0
percentages of system CPU time: .1.3.6.1.4.1.2021.11.10.0
raw system cpu time: .1.3.6.1.4.1.2021.11.52.0
percentages of idle CPU time: .1.3.6.1.4.1.2021.11.11.0
raw idle cpu time: .1.3.6.1.4.1.2021.11.53.0
raw nice cpu time: .1.3.6.1.4.1.2021.11.51.0

Thanks,
Subbu

According to this link, the OIDs which say "percentage of . . " have been deprecated in favour of the other OIDs. http://www.net-snmp.org/docs/mibs/ucdavis.html

So, you can use:

CPU
raw user cpu time: .1.3.6.1.4.1.2021.11.50.0
raw system cpu time: .1.3.6.1.4.1.2021.11.52.0
raw idle cpu time: .1.3.6.1.4.1.2021.11.53.0
raw nice cpu time: .1.3.6.1.4.1.2021.11.51.0

If you want the total, you can monitor the above OIDS then create a calculated Item to give the total of all the above. http://www.zabbix.com/documentation/1.8/manual/config/items#calculated_items

Hi Mrken,
I want to monitor the Memory of the linux server through SNMP , I tried with the below procedure and unable to find the total memory , please find the procedure which i followed and help me out


1. Did SNMP WALK 1.3.6.1.4.1.2021.4.5.0
2. hrStorageDescr.2 = STRING: Real Memory
3. hrStorageSize.2
4. hrStorageAllocationUnits.2 = INTEGER: 1024 Bytes

For refernce please find the attcachment .


Thanks,
Subbu

[MrKen]

subba5678,

Please read your last post very carefully. Are you trying to monitor Memory or DiskSpace?

hrStorage has nothing to do with Memory.


$ snmpget -v 1 -c private localhost .1.3.6.1.4.1.2021.4.3.0
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 1024120

$ snmpget -v 1 -c private localhost .1.3.6.1.4.1.2021.4.4.0
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 1012492

$ snmpget -v 1 -c private localhost .1.3.6.1.4.1.2021.4.5.0
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 223156

$ snmpget -v 1 -c private localhost .1.3.6.1.4.1.2021.4.6.0
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 7992

Hi Mrken,

Thanks for the help and i am able to monitor the Memory Utilization . I created a template to monitor the CPU Utilization , it worked for me , but its showing some value as " M " , Please find the attachment of my template and please help me out .
SNMPWALK :

UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 2106946


Thanks,
Subbu

[MrKen]

Use multiplier: Custom multiplier
Custom multiplier: 0.01

Store value: Delta (simple change)

[subba5678]

Hi Mrken,

Thanks for the update and its working fine , With this i created a trigger if the maximum cpu utilization is more than 80% per hour then i require a trigger , please look into the trigger , if it is wrong help me out

{TAL900:ssCpuRawSystem.0.max(3600)}>80

Thanks,
Subbu
