Could not find any matching data on this device. (code: PE187)

Hello I Enabled SNMP on my Esxi 6.0 Servers and add some SNMP Sensors like CPU load,Uptime,Network Traffic &... But when I try to add SNMP Memory it returns the below Error: Good to mention I restart SNMP Service but it doesn't have any result.

Could not create the sensor SNMP Memory on device MyEsxiServer.myDomainl.com (MyEsxiServer.Mydomain.com).

Could not find any matching data on this device. (code: PE187) Please check the following resources:

It might not work to query data from a probe device via SNMP (querying localhost, 127.0.0.1, or ::1). Add this device to PRTG with the IP address that it has in your network and create the SNMP sensor on this device instead. For a general introduction to the technology behind SNMP, please see the manual section Monitoring via SNMP.

Hi Sara,

It might be more sufficient for you to engage the VMware SOAP API to engage with VMware and read the data you are looking for. Did you try this already as alternative?

This specific sensor could be found here: https://www.paessler.com/manuals/prtg/vmware_host_performance_soap_sensor

Do you have a single ESXi host or a vCenter cluster?

Hello Sara,

I can confirm that Florian's suggestion is quite good. The VMware Host Performance (SOAP) Sensor even combines multiple of your requested queries in one sensor.

Best regards,
Sebastian

Hello Sebastian & Florian

I use VMware Host Hardware Status (SOAP) sensor for my hardware elements and SNMP for performance.yes you are right I can use VMware Host Performance (SOAP) but my question is why other SNMP items like COU load and Free disk work with SNMP but I get an Error when I add SNMP Memory.

Do you have any idea?

Check if you are using the right OID - use a SNMP test tool - do a SNMP walk if necessary.

It is likely that it OID you are using for Memory is outdated or changed the response.

Hi Sara,

The SNMP Memory sensor queries the OID 1.3.6.1.2.1.25.2.3.1.

As Florian recommended, download our latest SNMP Tester and execute this tool on the same probe that should has the sensor later on.
Please configure the SNMP settings properly and select Walk as request type. Please run a walk on the above mentioned OID and check what values the device answers here.

Best regards,
Sebastian
