date/time 12 hour format in nagios xi notification

[gcrodaje]

Hi,

Is there a way to change the notification date/time to 12 hour format?

example:
from
Date/Time: 2019-01-23 15:29:33 HKT
to
Date/Time: 2019-01-23 03:29:33 PM HKT

Thank you.

This question has been asked before. It's not so easy to change to format to 12 hour in Nagios Core. See the discussions below:

https://support.nagios.com/forum/viewto ... =7&t=41438

Having said that, there could be a way to modify the notification command and/or the notification messages somehow to convert the format. From the command line, you could use something like this:

Code: Select all

date +"%F %r %Z"
2019-01-24 12:57:37 PM CST

but I haven't been able to use that in Nagios XI to change the format, at least not yet. I will keep the topic open in case someone wants to chime in and offer a better solution.

Hi lmiltchev ,

I will try to replace the $LONGDATETIME$ with date +"%F %r %Z" as suggested. Will let you know the result.

Thank you very much.

We will keep this topic open for the time being. Let us know if you had any luck with converting the date/time format. Thank you!

Hi lmiltchev,

No effect on the time format. I also tried to use date +"%c", but i have no luck.

May i know if the Nagios XI is dependent on the NMS system clock? In my case, i used CentOS 7 for my NMS which i'm trying a several research on how to change the default system clock to 12-hour clock format, though the gnome desktop is already set to 12-hour format, but when i use the terminal, it always print the 24-hour.

Also, is there a way to create a new command to use as macro like $LONGDATETIME$ so i can change it to date +"%c".

Another thing, how to post on the customer support section because we have this client who already renewed their nagios subscription but i have no idea how to escalate an issue to nagios support.

For your kind advise, please.

Thank you very much.

No effect on the time format. I also tried to use date +"%c", but i have no luck.

After doing some more testing, I found out that converting the time format would be possible ONLY if you used a custom notification handler. For example, you could modify the Nagios Core notification handlers, (e.g. "notify-host-by-email" and "notify-service-by-email"), and used these instead of the "default" xi handlers ("xi_host_notification_handler" and "xi_service_notification_handler").

Example:
1. I set up a user macro in the /usr/local/nagios/etc/resource.cfg file:

Code: Select all

$USER9$=`date +"%F %r %Z"`

2. I modified the "notify-host-by-email" command as such:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $USER9$\n" | /bin/mail -r [email protected] -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$ 

3. The notification that I received looked like this:

Code: Select all

***** Nagios Monitor XI Alert *****

Notification Type: PROBLEM
Host: MyTestHost
State: DOWN
Address: 192.168.x.x
Info: test

Date/Time: 2019-01-28 12:35:51 PM CST

I am not familiar with NMS, but we use whatever php uses as time settings for the system clock.

Yes, you could use a custom command with a user macro, placed in the resource.cfg file (as shown above).

Another thing, how to post on the customer support section because we have this client who already renewed their nagios subscription but i have no idea how to escalate an issue to nagios support.

Hi lmiltchev,

Thank you for your prompt response.

I will try to set up a user macro as suggested. Will let you know the result.

Thank you very much!

[lmiltchev]

You are welcome! Let us know how it went.

Hi lmiltchev,

I tried these steps, but it didn't work for me. Please see action taken below.

1. I set up a user macro in the /usr/local/nagios/etc/resource.cfg file:

Code: Select all

$USER9$=`date +"%F %r %Z"`

Is it ` or ' ?

example:
$USER9$=`date +"%F %r %Z"` or
$USER9$='date +"%F %r %Z"'

either way, I tried both, but no effect.

2. I modified the "notify-host-by-email" command as such:

Code: Select all

/usr/bin/printf "%b" "***** Nagios Monitor XI Alert *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $USER9$\n" | /bin/mail -r [email protected] -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$ 

I modified the "notify-host-by-email" as well as the "notify-service-by-email".

3. In the core config manager, select services, select config name and then check settings > enable event handler then select notify-service-by-email. (I also tried to select other like xi-service-notification-handler which I also modify the command from $LONGDATETIME$ to $USER9$) and then save settings.

4. Check service status > advanced > then send custom notification.
This is what I get.

Code: Select all

***** Information Technology Alert *****
***** SERVICE ALERT *****

Date/Time: 01/31/2019 14:14:20

Notification Type: CUSTOM
State: WARNING

Host: testhost
Address: 192.168.x.x

Service Affected: Drive C: Disk Usage

Additional Info: 

C:\ - total: 232.79 Gb - used: 197.83 Gb (85%) - free 34.96 Gb (15%)


***** Nagios Monitoring System *****
***** Centos ver. 7; NagiosXI ver 5.5.7*****

As you notice, the date/time still the same. I tried also to restart the services, but same output.

Thank you.

btw, for additional information, we're using SMTP and not sendmail in the managed email settings in Nagios XI.

Based on https://assets.nagios.com/downloads/nag ... Mailer.pdf

Core Notification Handlers:
Nagios Core notification commands - notify-host-by-email and notify-service-by-email. The handlers use sendmail exclusively and will not work with the XI SMTP settings.
XI Notification Handlers:
Nagios XI notification commands - xi_host_notification_handler and xi_service_notification_handler. These handlers use the Nagios XI SMTP settings but require that the contact was created as an XI User Contact.

Thank you very much.
