Zabbix icmp pinger processes more than 75% busy

In zabbix the icmp pinger is a process that pings your hosts or devices that you have added to the system. What I have found is that it will fall behind when you add more hosts for it to ping such as printers, servers, computers, network devices.

I have found that increasing the value of the StartPingers in the zabbix configuration file will solve this issue.

  1. SSH into your zabbix server and enter your login credentials.
  2. Edit the “zabbix_server.conf” file (vi /etc/zabbix/zabbix_server.conf)
  3. Find the section “Option: StartPingers”
  4. Edit or add a line of “StartPingers=(value)”
  5. Save the file “:qw”
  6. Restart the zabbix server (service zabbix_server restart)

 

Zabbix: Too Many Process on Zabbix Server

I have ran into this a couple times of when adding many checks and services to the Zabbix server.

Trigger: Too many processes on Zabbix server Trigger status: PROBLEM Trigger severity: Warning Trigger
Item values:
1. Number of processes (Zabbix server:proc.num[]): 354

What I have found to remedy this issue is change the trigger for the Processes Monitor.

  1. Click on Configuration
  2. Click on Hosts
  3. Find the Zabbix Host
  4. Under triggers column click “Triggers”
  5. Locate the “Too many processes on {HOST.NAME}” and click on that link
  6. Since the trigger is connected to a template you will need to click on the Parent Triggers template link.
  7. In the expression field change the value above of what the it is triggering at.
  8. Save the Trigger and that should resolve your issue.

Hope this helps in curing the alert. In my instance I have added more Pollers, Pingers and Discovers to many config which raised my amount of processes on the server. If you didn’t any of such make sure you check to why there is more processes on the server.

 

Websense Hosted Web Security Allow Certain YouTube Videos

I recently came across a interesting problem with the Websense hosted security and allowing just certain streaming videos from YouTube to be viewed. What I came across is that with a website it has a embeded YouTube video in the website and the user needed to play it. By default if you have streaming media blocked you wont be able to access anything on the streaming video site YouTube.

  • The setup is they are using the hosted endpoint client installed on the computers.
  • In the Websense online program you will login and create a new Custom Category under the Policies Management.
  • Name the Category accordingly “YouTube Allowed”
  • Add the following sites to the category (please note that these may change by site)
    1. c.youtube.com
    2. i1.ytimg.com
    3. i1.ytimg.com/crossdomain.xml
    4. s.youtube.com
    5. s.ytimg.com
    6. www.youtube.com/crossdomain.xml
    7. www.youtube.com/get_video_info
    8. youtube.com/crossdomain.xml
    9. ytimg.com
    10. youtube.com/embed/ (youtube unique id for video)
  • Note that each YouTube video has a unique id so find that id and apply it accordingly.
  • Once the custom category is completed go to Policies.
  • Select the policy that you are wanting to allow the YouTube videos on.
  • In the web policy that you selected click on the “Web Categories” tab.
  • Under the custom categories select the YouTube category that you created.
  • In the actions section click the “Allow Access” (with the allow access it will ignore any other blocking category.

 

This is the first revision and will be updated in the future.
I wanted to get others this information to assist them and if you have anything that you want to add be sure to send me a message or comment on this post.

Fully Automated Nagios

I have changed jobs recently and was given the task of building a network monitoring system.

Check out http://fannagioscd.sourceforge.net/

It is a complete setup that all you have to do is download the ISO, burn the DVD and start the installation.

In the installation process it installs Nagios with supporting packages of Centreon and NAGVIS.

Check it out and I will be updating these posts as I get more done in the project.

If you would like to add a article to this site please contact me and I will be willing to work with you.
