error in running python plugin

[magpantayr]

Hello,

I am monitoring our NetAPp filers Storage consumption with netappfiler.py plugin and is running properly for months

But after I followed this guide coz I am trying to make my oracle monitoring work (https://assets.nagios.com/downloads/nag ... ios-XI.pdf),
suddenly all of my services that uses this python plugin encountered error ( see code below)

Code: Select all

I also attached the plugin I am using.

Thanks!

This looks like it is not executing through python, or cannot determine the path to python from the shebang line

Code: Select all

/usr/bin/env python

Can you run

Code: Select all

python /usr/local/nagios/libexec/check_netappfiler.py

Hello,

Putting python in the start did work. I just updated the command and included it.

Thanks for the support.

ANyways, do I need to include python in all my future commands that uses python?
Is there anyway I can fix the python not executing from the shebang line?

Thanks again!

ANyways, do I need to include python in all my future commands that uses python?
Is there anyway I can fix the python not executing from the shebang line?

The alternative is to put the full path to python in the shebang line, you can get it by running

Code: Select all

# which python
/usr/bin/python

Then change the shebang to

Code: Select all

#!/usr/bin/python

Hello,

Thanks for this! I've updated the python script.

I also noticed that my Oracle plugin did not work also (it is also using the /usr/bin/env) at the command line.

This is also working before

Code: Select all

/usr/bin/env LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib ORACLE_HOME=/usr/lib/oracle/12.1/client64 $USER1$/check_oracle_health $ARG1$ --tablespace $ARG2$

Result:

Code: Select all

(No output on stdout) stderr:

I think all my commands that using /usr/bin/env is not working properly. How can I check this?

Thanks!

It's possible that you have a broken symlink. Can you show us the output of the following commands?

Code: Select all

which env
ls -lL /usr/bin/env
env | grep -i oracle

[magpantayr]

Hello,

This is the output:

Code: Select all

[root@CBAS035A ~]# which env
/usr/bin/env
[root@CBAS035A ~]# ls -lL /usr/bin/env
-rwxr-xr-x. 1 root root 0 Mar  4 16:46 /usr/bin/env
[root@CBAS035A ~]# env | grep -i oracle
[root@CBAS035A ~]#

You will need to add the ORACLE_HOME and the LD_LIBRARY_PATH to your environment. If you haven't upgraded the oracle client, e.g. you are still using 12.1 and these paths didn't change:

Code: Select all

LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib 
ORACLE_HOME=/usr/lib/oracle/12.1/client64

you could run:

Code: Select all

export ORACLE_HOME=/usr/lib/oracle/12.1/client64
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib

In order to make the change permanent, you could place a script, named oracle.sh in /etc/profile.d, which contains the same commands:

Code: Select all

export ORACLE_HOME=/usr/lib/oracle/12.1/client64
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib

Reboot, and check to see if oracle home and library paths are added to your environment:

Code: Select all

env | grep -i oracle

Are you still using the 12.1 client? What is the output of the following command?

Code: Select all

ls -la /usr/lib/oracle/

[magpantayr]

Done running the export command and creating oracle.sh inside the /etc/profile.d

But after reboot, I run the env | grep -i oracle but no output

Code: Select all

[root@CBAS035A ~]# env | grep -i oracle
[root@CBAS035A ~]#

But the export seems to be working

Code: Select all

[root@CBAS035A ~]# echo $LD_LIBRARY_PATH
/usr/lib/oracle/12.1/client64/lib
[root@CBAS035A ~]# echo $ORACLE_HOME
/usr/lib/oracle/12.1/client64

and yes, I still using oracle 12.1 client

Code: Select all

[root@CBAS035A /]# ls -la /usr/lib/oracle/
total 4
drwxr-xr-x   3 root root   18 Oct 11 13:20 .
dr-xr-xr-x. 32 root root 4096 Oct 11 13:20 ..
drwxr-xr-x   3 root root   22 Oct 11 13:20 12.1

[lmiltchev]

But after reboot, I run the env | grep -i oracle but no output

This is strange as the oracle home and library path were set in your environment... Anyway, can show us the actual check run from the command line along with the output of it?

Note: I believe you need to have " --mode <arg>" added to your command, for example:

Code: Select all

/usr/bin/env LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib ORACLE_HOME=/usr/lib/oracle/12.1/client64 /usr/local/nagios/libexec/check_oracle_health --connect 'x.x.x.x:1521/xxx' --username '<username>' --password <password>' --mode tablespace-usage --tablespace USERS

If the command fails, try adding "-v" at the end for increased verbosity, and show the output.
