Hi, I'm testing monitoring of EMC Datadomain and you can monitor nearly everything with the OIDs: https://www.emc.com/collateral/TechnicalDocument/docu78751.pdf

But I don't want to have so many sensors on my device. There is the OID 1.3.6.1.4.1.19746.1.4.1.1.1 which is a table with all active alerts...but there is noting in the Table if everything is ok...how is it possible to get a sensor counting the rows...and display the text of the alert:

  • 1.alert: 1.3.6.1.4.1.19746.1.4.1.1.1.3.1 eg. "Active tier is low on spares"
  • 2.alert: 1.3.6.1.4.1.19746.1.4.1.1.1.3.2 e.g. "Unable to access a disk" and so on...

Regards Chris

Hello Chris,

Thanks for your inquiry, we appreciate your contact regarding this matter!

Unfortunately it is not possible to count SNMP rows in PRTG by default. A possible workaround would be to walk the table using a PowerShell script and get the number of entries back as integers accordingly. These could then be evaluated with an EXE Script sensor and correspondingly defined limits.

Here is an example which works similarly: https://kb.paessler.com/en/topic/25313-sensor-for-bgp-status

For any further questions or issues, we're glad to help.


Kind regards,
Birk Guttmann, Tech Support Team
