Thanks for update,

Now i'm getting one more issue
for the below issue.
tail -f /usr/local/nagios/var/npcd.log

Code: Select all

we changed following parameters but no luck .

in

Code: Select all

/usr/local/nagios/etc/pnp/process_perfdata.cfg

1. TIMEOUT = 40
2. load_threshold = 40.0
And
uptime

Code: Select all

[root@nagihpcorp01 ~]# uptime
 12:01:59 up 7 days,  5:20,  2 users,  load average: 6.88, 8.88, 9.80
[root@nagihpcorp01 ~]#

This can get logged on even healthy systems if the file was processed by another thread.

Are you missing performance data from any graphs?

[cdienger]

How frequently is this occuring? How many CPUs are on the system? What version of XI is this?

You can enable debugging for npcd by setting:

LOG_LEVEL = 2

in

/usr/local/nagios/etc/pnp/process_perfdata.cfg and then restart the npcdprocess with "service npcd restart"

[Gonela]

still getting same error after changed in the process_perfdata.cfg file and also missing of performance graphs frequently

Also getting following error in the /var/log/messeges

XI Version : 5.5.3

CPU Cores : 16

RAM : 16GB

OS : Centos 7

Setting up a ramdisk can improve the performance of perfdata processing. It's easy to set up too using the script and steps found in https://assets.nagios.com/downloads/nag ... giosXI.pdf.

[Gonela]

Thanks for update,

As of now , no issues once we implemented Setting up a ramdisk.

We mentioned RAM Disk Size - 500MB during installation. In future , if we want to increase RAM Disk Size . How ?

[tgriep]

To increase the RAMDISK size on the system, you would edit the following file on the Nagios server.

Code: Select all

/etc/sysconfig/nagios

Then edit this option and increase to the size you need.

Code: Select all

RAMDISK_SIZE=500

Save the file and reboot the server so the system can recreate the RAMDISK in the larger size.

Hi ,

Again performance graphs are missing for some servers and some interval of time .

Screenshot attached

[tgriep]

Can you post the following files from the Nagios server so we can view the performance data errors it there are any?

Code: Select all

/usr/local/nagios/var/perfdata.log
/usr/local/nagios/var/npcd.log

Then, run the following as root and post the output here.

Code: Select all

/usr/local/nagios/bin/nagiostats
ipcs -q
ps -ef --cols=300

Thanks

All commands output attached for review.
