No MongoDB metrics after upgrade from 2.9.1

Percona Monitoring and Management (PMM) PMM 2.x
1

Hello

I have exactly the same problem as https://forums.percona.com/discussion/56527 but I can’t reply there :frowning:

pmm-admin 2.9.1:

netstat -alnp | grep LISTEN -w

…

tcp6 0 0 :::42001 :::* LISTEN 7427/mongodb_export

…

curl -s -u pmm:/agent_id/f2e8e21c-5ca0-4f9f-bd6f-4c92767ffc27 http://localhost:42001/metrics | grep mongodb_version

HELP mongodb_version_info Software version information for mongodb process.

TYPE mongodb_version_info gauge

mongodb_version_info{mongodb=“3.6.21-10.0”} 1

The same server after upgrade to pmm-admin 2.12.0 (mongodb_exporter’s port was changed to 42002):

netstat -alnp | grep LISTEN -w

…

tcp6 0 0 :::42002 :::* LISTEN 7025/mongodb_export

…

curl -s -u pmm:/agent_id/f2e8e21c-5ca0-4f9f-bd6f-4c92767ffc27 http://localhost:42002/metrics | grep mongodb_version

HELP mongodb_version_info The server version

TYPE mongodb_version_info gauge

mongodb_version_info{mongodb=“server version is unavailable”} 1

The same server after downgrade back to 2.9.1:

curl -s -u pmm:/agent_id/f2e8e21c-5ca0-4f9f-bd6f-4c92767ffc27 http://localhost:42001/metrics | grep mongodb_version

HELP mongodb_version_info Software version information for mongodb process.

TYPE mongodb_version_info gauge

mongodb_version_info{mongodb=“3.6.21-10.0”} 1

What’s wrong with it? Thank you

Hi Andrii,

Thank you for your ticket refer the issue.

Until the issue has not fixed please consider using the old version of exporter.
