Hello

I have exactly the same problem as [https://forums.percona.com/discussion/56527](https://forums.percona.com/discussion/56527) but I can’t reply there ☹

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](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](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](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.
