Linux SNMP Memory Check - Reported Memory is incorrect

[dslaughter]

https://www.linuxatemyram.com/

check_snmp_storage_wizard.pl reports incorrect free memory. I searched and there a lot of posts reporting this. Is this bug going to be fixed?

I've found a plugin that reports memory correctly - check_snmp_mem.pl. I use the snmp wizard so I need to remove the broken plugin and replace it with the plugin that reports memory correctly. What it the proper way to do this? I can edit the config.xml of the plugin but is that the correct way to do it? It seems like I should be able to do this in CCM.

Wrong
check_snmp_storage_wizard.pl
Physical memory: 34%used(1272MB/3789MB) (<50%) : OK

Correct
check_snmp_mem.pl
Ram : 18%, Swap : 0% : ; OK

Thanks for the suggestion. I'll look into updating the wizard.

An updated wizard is attached. Please test and let me know your thoughts.

I installed the update and performed a test. I'm getting configuration verification failed.

Updated and attached.

I did a quick test but got the same error. I may have bungled the update. I've got to wait til tomorrow before I can look at this again. Thank you for your help. I'll send an update tomorrow to let you know how it went.

[dslaughter]

I downloaded the file again to make sure I was using the correct one. I got configuration verification failed again. Command output was the same.

[cdienger]

Those may be from the previous config. Try restoring to a good config(Admin > Monitoring Config > Config Snapshots) and make sure that that can apply before running the wizard again.

[dslaughter]

Sorry for the late reply,

I restored the snapshot but when I used the linux-snmp wizard it just setup the original memory check. I've got some time later today to try this again. I'll restore a snapshot, downlod the updated wizard again and then give it another go.

[cdienger]

Let me know your results and I'll try the same on a clean system. It's possible that through my testing I have configs in place that another system may not.
