Sounds good. If you have already sent it, can you send it once more ( my inbox was full). Thanks, Benjamin

Hi,

That looks correct, are you still not able to download the profile for the GUI? How often is the monitoring engine stopping right now?

It's not common for the Nagios process to die or crash. Can you re-send a fresh system profile (I was unable to retrieve it in the PM message system)? Thanks, Benjamin

Generating a Profile fom the Command Line

Code: Select all

rm -rf /usr/local/nagiosxi/var/components/profile*​​
/usr/local/nagiosxi/scripts/components/getprofile.sh SUPPORT

Then send me the resulting /usr/local/nagiosxi/var/components/profile.zip​ file.​

Hi Benjamin,
Even for this instance i m not able to download the profile from GUI..

We are getting frequent swap and memory alerts for Nagios VM... and monitoring engine process keep fluctuating.. swap space almost goes down to 0%.. then if i restart the monitoring engine process, it again picks up... and this keeps going on...

the 2 commands u mentioned, needs to be ran separately?

this DF -h output:

Hi,

the 2 commands u mentioned, needs to be ran separately?

The first command is optional. If you run the following command:

Code: Select all

/usr/local/nagiosxi/scripts/components/getprofile.sh SUPPORT

Make sure you retrieve the most recent profile form the following directory:

Code: Select all

/usr/local/nagiosxi/var/components/

Also, if you have enough memory, it should not need the swap space. Can you increase the RAM on this server as it's probably not sufficient?

[pratikmehta003]

Sure, i will run that and send u..

and have asked customer to increase RAM

[benjaminsmith]

HI,

Sounds good. You can send the profile as a private message (PM) or attach it to the thread.

[pratikmehta003]

sure.. give me sometime.. working with customer on it

[benjaminsmith]
