I would like to include following information in my varnishncsa logs (I need to relate some issues with specific users).
After reading https://www.varnish-cache.org/docs/trunk/reference/varnishncsa.html I am not really sure how I can achieve it.
BTW, I am not able to add the "varnishncsa" tag to the question - someone can add it (with higher reputation? :P).
I have working nagios infrastructure with pnp4nagios. Last days I added new host nosql and alerts of mongodb which is installed there.
Host configuration:
define host{
host_name nosql
use linux-server,host-pnp
address xxx.xxx.xx.xxx
}
Service configuration:
define service{
hostgroup_name nosql-servers
use generic-service,pnp-service
service_description MongoDB Connect
check_command check_nrpe!check_mongo_connect
}
They seems to be configured in same way like the others one. However, when I am trying to access graph in pnp4nagios I got:
Please check the documentation for information about the following error.
XML file "/usr/local/pnp4nagios/var/perfdata/nosql/MongoDB_Connect.xml" not found. Read FAQ online
file [line]:
application/models/data.php [312]:
I am a bit help.
How I should activate new graphs?
Today I noticed that my LDAP server (OpenDS) consumes 100% CPU on every available core. Fast diagnose showed me that there is a lot of ETIMEDOUT during the futex lock.
How Can I debug it to figure out what is happening and how to fix it?

Not sure if its related - but I noticed also that Redmine (Ruby app) have similar "feature"... Help :)
I am using pnp4nagios along with the nagios.
Everything seems to be integrated properly - I have "extra action" icons close to every host and service which links to pnp4nagios graph.
However, when I am going to the https://x.x.x.x/pnp4nagios/ it always change the url to the:
https://x.x.x.x/pnp4nagios/graph?host=webhost01
How Can I turn off this behaviour?
I would like to see on /pnp4nagios/ collected graphs from all servers.
I have configured several repositories on my CentOS 5 box. As an effect, command:
yum search nagios
outputs just mess - thousands of duplicated packages.
To make my life easier I would like for example to search for package nagios only in specific repo, like rpmforge and with minimum version '3', for example.
How can I achieve this?
30 minutes ago my router is not accepting ssh connection. Well, ports is open (due to nmap), ssh simply hangs on reading from Cisco socket (observation from strace):

Where 3 is file descripor of connection with router (ESTABLISHED state, due to the netstat).

One hour ago I was still able to connect. Now there is no more access trough the console port - what I should do?
i am configuring DHCP daemon on Cisco 2911.
At some point i assigned address 192.168.50.50 to one box (using MAC address 'relation').
When I wanted to saved config - I got warning, that address 192.168.50.50 is already in Pool, which sounds bit weird - it was first host which I started configuring.
I tried with following commands:
clear ip dhcp server statistics
clear ip dhcp conflict
but first one doesn't output anything (and show statistics shows that there are 2 addresses in pool), and second one throws "there is no conflicted ips" message.
How I can force/purge/clear/allow to bind 192.168.50.50 to this box?
I briefly configured branch router Cisco 2911 and saved config.
Unfortunately - after rerun Cisco needs "copy startup-config running-config" to read configuration (I really need this - for example to get up interface GigabitEthernet0/0).
How I can save my configuration as the permanently one and auto started?
