mysql probe fails to start on linux robot and produces "max restarts" error in controller log.

(Example: "Controller: Max. restarts reached for probe 'mysql' (command = mysql)").

The probe may even turn green in Infrastructure Manager, but not get a port or pid and eventually turns red error state.


Determined there was a missing shared library rpm package (such as: compat-libstdc++)
(Note - Some recent Linux distributions come with newer versions of the C++ libraries and some probes depend on older libraries or updated libraries).


Release : 9.2.0+

Component : UIM MYSQL 1.51 T1/ 1.51 or higher


Please take the following steps to determine if this is the issue and see what package the probe is looking for:

1. De-activate mysql probe.

2. On the Linux machine, go to the probe mysql folder on the system and provide the output of the following ldd command:

 ldd  mysql_monitor

In this instance, this is the missing library: => not found

3.Research the particular version for your particular Linux version to find a correct install command:

# yum install compat-libstdc++-[particular version... such as 33.x86_64]

#  yum provides */ANY_FILENAME_GOES_HERE
Make note of the rpm that results from that output and consider installing it.

# yum provides */

4. Run the command and install the package.

5. Recheck ldd for the mysql_monitor binary if failing on the shared lib dependency

6. Activate the mysql probe or redeploy again from the local archive and it should now work.

One Exception:
RHEL8 does not provide  It has been attached to this KB.  Please copy this file in the path "/lib64/" in the RHEL8 machine and redeploy the mysql probe.  This requirement will be updated to version 6 in the probe versions after mysql 1.60.

Additional Information

Currently, only MySQL v5.x is supported not 6.
