Nagios STATE = RSZDT

nibraz · 10-18-2016, 03:49 AM

I am constantly receiving this below message from Nagios to my email about 10 or more times a day..

Is this something I need to worry about? anyway to reduce the amount of times i get the email?

Thanks

Code:

[10-18-2016 09:03:18] SERVICE ALERT: localhost;Total Processes;WARNING;SOFT;3;PROCS WARNING: 252 processes with STATE = RSZDT
Service Warning[10-18-2016 09:02:18] SERVICE ALERT: localhost;Total Processes;WARNING;SOFT;2;PROCS WARNING: 253 processes with STATE = RSZDT

It's your Nagios, turn off the alert if you don't want to get the e-mail.

You might want to read this for more info: https://support.nagios.com/forum/vie...hp?f=6&t=22008

I read that forum from nagios but couldnt understand what exactly this error indicates or what I should do to resolve it.. they said to increase the warning threshold but not sure how to do that.. any idea what this error means?

Thanks

If you don't understand the alert or what you should do to resolve it, why bother configuring it?

That alert is the total count of processes that are running, and what's normal for your server can vary VASTLY. For example, there will be a number of worker processes that will increase depending on the number of CPUs/cores that the hardware has.

As you've provided no information on your server spec or what it's running there's no clue to what would be normal for it.

My server is a webserver that is running for the past 6 years.

Its on Centos 6.5
8GB Memory
Intel Xeon 2.5GHZ 8 Cores
200GB SSD Hard Drives

I have mysql, apache and services that is mainly for my webserver.

I have increased the check_command as below:
check_command check_local_procs!544!744!RSZDT

Not sure if this will resolve the issue.

Just a few minutes' Google searching will show you what the various letters that make up "RSZDT" means, and likewise what this Nagios filter's settings mean.

(The letters correspond to specific bits in the wait-reason mask ...)

I don't find this particular setting very useful because, as others have said, the "total number of processes" can vary wildly from moment to moment, depending on exactly what your server is doing and for whom. Nagios installations customarily include it, but I customarily turn it off.

What is of more concern to me would be specific bottlenecks. A very large number of processes that are waiting on a particular thing. A large number of processes in a non-idle wait state, indicating that they are otherwise ready to proceed but cannot. Not just waiting for "any" thing, but waiting for "very specific" things.

I suggest that it is fairly useless (but, very common) to configure Nagios to "squawk" about things that might be an issue. Instead, you should formulate very clear notions of exactly what sort of thing would require your intervention or at least your attention, and configure Nagios to vigilantly look for that.

If Nagios is, in effect, "spamming your mailbox" about things that do not cause you to immediately take a specific action, then it is ... well ... just "spamming your mailbox," and you should stop it. You've got an electronic "Boy Who Cries 'Wolf!'"
