Unexpected error occurred. KeyError: 'getpwuid(): uid not found:

We have several linux monitors that are monitoring the SNMPD process on our linux servers and solarwinds is giving us this error message Unexpected error occurred. KeyError: 'getpwuid(): uid not found: 1000060000' or Unexpected error occurred. KeyError: 'getpwuid(): uid not found: 65534.'

I've checked on the node and the snmpd process is running.

I've looked into the /etc/passwd file and the UID in the error message is not in there. I know that both of the accounts associated with those UID's in the error messages are system accounts.

Not quite sure how I can change it to use the proper system account.

Other useful information: we are using the Linux Agent, and this is just a basic process monitor.

Any help appreciated.

I would turn on debugging and see if you can't track down the issue from the logs.

We have just had this after upgrading the swiagent on a load of linux hosts..

Try the following:

Stop the swiagent process via

systemctl stop swiagentd / service swiagentd stop or whatever for youe environment.

Edit the process helper python file below

either vi /opt/SolarWinds/Agent/bin/Plugins/APM/process_helper/process_helper.py

or vi /opt/SolarWinds/Agent/bin/Plugins/APM/process_helper.py
depending on the agent version

Find the following section

----------------------------------

def get_user_name(cache, uid):

if uid in cache.keys():

return cache[uid]

user = pwd.getpwuid(uid)[0]

cache[uid] = user

return user

----------------------------------

and replace it with this.

-----------------------------------

def get_user_name(cache, uid):

try:

user = pwd.getpwuid(uid)[0]

except KeyError:

user = 'root'

return user

-----------------------------------

Start swiagentd again and process explorer should work.

Just checking - did you have to do this with the latest version of SAM e.g. 2019.4?

stevenstadel

No, we are currently on 6.9.1

FYI I am getting this error with a CentOS box monitored via the agent on 2019.4. I'll work on implementing the fix above. @serena has this already been confirmed as a recurring issue in the latest release?

*EDIT*

Confirmed that the fix above works. Seems this is still an issue in 2019.4
