Issue with email format

[stecino]

Hello,

In the status information of the service, I have a multiline message, but when the email notification is sent out it's in one line. Is there a way to fix it.
Even in my python code I add carriage returns to each line gets printed, but that didn't fix it.

Thanks in advance

Can you show us an example of your multiline message and what you actually receive as a notification? Also, show us the notification command that you are using.

Attached is a screenshot from the nagios ui, where you can see the multiline status information


Here is the email body, where the same status info is not multiline

What is the version of Nagios Core that you are using?

I was not able to recreate the issue. I tested the multiline in Nagios XI, but I am running Nagios Core 4.0.8 underneath. The $LONGSERVICEOUTPUT$ seems to work fine for me.

From the CLI:

Code: Select all

./check_disk -w 20 -c 10 -A -n
DISK OK - free space:
 / 9227 MB (55% inode=91%);
 /dev/shm 938 MB (100% inode=99%);

In Nagios Core:

Nagios Core 3.5.1

Is there a chance that you spin up a test VM with Nagios Core 4.0.8 and test your check there? If the issue is resolved in Core 4, you can possibly upgrade.

Unfortunately, it's not the best option for me right now. Initially I had Nagios Core 4.0.x installed, but it turned out not to be compatible with PNP4Nagios2.0, so the only solution based on different boards was to downgrade to latest 3.x.
Is there a workaround for this? Maybe creating a custom Macro that may add carriage returns prior to sending out?

This doesn't really answer your question - but just to satisfy the curiosity of an unknowing support forum tech - what is PNP4Nagios2.0?

More to the point of solving your problem - are you certain you're using the command you posted? I have a lot of Core 3.5.x experience and it always has (and still today) sends me multiline E-mails just fine using the default notify-by-email commands. I would double check your contact definition.

pnp4nagios is the graphing add-on for nagios, that graphs the performance data. Yes that's the command I am using.

Do you have any other multi-line plugins running and are they working?
Can you run your check from a shell on your server and post the output here?
Can you upload your script so we can review it?
