Did you know that you can monitor redis commands live from within
Go to redis client by typing
It will log everything that happens on your redis server.
#redis #redis_cli #cli #monitor
redis-cli console?Go to redis client by typing
redis-cli in terminal and then type monitor command and enter:127.0.0.1:6379> monitor
OK

It will log everything that happens on your redis server.

How to monitor network cards on
Yesterday I've been on a task of monitoring network cards of all our servers and infrastructure to check the bandwidth in/out and send alarms based on some criteria. In
Move the script to
Some important usages of the script:
- list interfaces of a specific server (we assume snmp has been installed on the destination server):
The output would be something like below (it can be different in your case):
The interface name is given in front of serial numbers which is
Another mode for the script is
OK, the important part is over and we can list all server network interfaces plus the usage of a specific network interface. In the next part we will explain the

Icinga2? (part-1)Yesterday I've been on a task of monitoring network cards of all our servers and infrastructure to check the bandwidth in/out and send alarms based on some criteria. In
Icigna2 we have a library from nagios called check_nwc_health. Download the script from https:// labs.consol.de/nagios/check_nwc_health/index.html.Move the script to
/usr/lib/nagios/plugins on a server that you have installed Icinga2. If you run it all alone you will get some helps that you could be useful.Some important usages of the script:
- list interfaces of a specific server (we assume snmp has been installed on the destination server):
./check_nwc_health --mode list-interfaces --hostname YOUR_TARGET_SERVER_IP --community YOUR_COMMUNITY_STRING
The output would be something like below (it can be different in your case):
000001 lo
000002 Device 1af4:0001 2
000003 Device 1af4:0001 3
000004 docker0
OK - have fun
The interface name is given in front of serial numbers which is
lo, Device 1af4:0001 2 or docker0. These interface names are important and will be used in icinga2 to add network card to hosts.Another mode for the script is
interface-usage that shows in/out bandwidth. The output can be something like follow:OK - interface Device 1af4:0001 2 (alias eth0) usage is in:0.00% (7058.67bit/s) out:0.00% (5603.67bit/s) | 'Device 1af4:0001 2_usage_in'=0%;80;90;0;100 'Device 1af4:0001 2_usage_out'=0%;80;90;0;100 'Device 1af4:0001 2_traffic_in'=7058.67;0;0;0;0 'Device 1af4:0001 2_traffic_out'=5603.67;0;0;0;0
OK, the important part is over and we can list all server network interfaces plus the usage of a specific network interface. In the next part we will explain the
Icinga2 part to add the command and the service to icinga2.#icinga2 #icinga #nagios #check_nwc_health #network #monitor
