Hello,

I am monitoring my Cisco ASA CPU utilization with PRTG. Its working fine for months but all of a sudden i am getting "No such object (SNMP error # 222)" . If i remove the sensor and add it again, it will start working fine.

asa cpu-load snmp-error#222

Hello,

which sensor you are using for the Cisco ASA CPU utilization?

If the error occurs the next time in PRTG again, please use our SNMP Tester, run it on the PRTG Host (or host of the Remote Probe), and perform a "Walk" to the OID "1.3.6.1" against the target device. Which results do you get in the Tester? Please send us the result logfiles from the Tester to [email protected] and refer to this KB-post.

I ran into this as well on an ASA5516 and found that I needed to use the "SNMP Cisco System Health Sensor". I had originally found that I could change the OID in the CPU sensor to 1.3.6.1.4.1.9.9.109.1.1.1.1.8.1, but later learned that was only monitoring 1 of 4 processors. Please see the response Paessler support gave me below. Using the "SNMP Cisco System Health Sensor" worked for me.

Your ASA appears to provide the OID's used by the "SNMP Cisco System Health Sensor", have you tried deploying this sensor? The sensor will try with 1.3.6.1.4.1.9.9.109.1.1.1.1.4, if not found it will use 1.3.6.1.4.1.9.9.109.1.1.1.1.7 which is available according to your walk file.

You should also be able to manually create the sensors for the following OID's:

1.3.6.1.4.1.9.9.109.1.1.1.1.8.1 = "3" [ASN_UNSIGNED]
1.3.6.1.4.1.9.9.109.1.1.1.1.8.2 = "3" [ASN_UNSIGNED]
1.3.6.1.4.1.9.9.109.1.1.1.1.8.3 = "3" [ASN_UNSIGNED]
1.3.6.1.4.1.9.9.109.1.1.1.1.8.4 = "3" [ASN_UNSIGNED]

The 1.3.6.1.4.1.9.9.109.1.1.1.1.8 OID stands for cpmCPUTotal5minRev.

Please mind that you need 4 sensor's because the device reports 4 distinct CPUs. The "SNMP Custom Advanced Sensor" should be able to measure all OID's in a single sensor, but using the "SNMP Cisco System Health Sensor" would be the appropriate solution.
