LES v2 incl. pre-installed TKmon: high 24x7 availability thanks to passive cooling and SSD (pricing see Thomas-Krenn-Shop)
This article shows how to set up a TKmon 2.1 monitoring system for the first time.

To use TKmon you can either buy a LES v2 incl. pre-installed TKmon or install TKmon on an Ubuntu server manually.

Login

Open a web browser and log in to TKmon:

Change the Password

For security reasons, change the password.

Call-Home-Service Set-Up

To use the Thomas Krenn Call-Home-Service perform the following configuration steps:

SMS Set-up

Attention: In order to use the SMS feature, a CEP CT63 Modem must be connected to your appliance!

Contacts Set-up

In the contacts area enter all the recipients, to whom the monitoring system should send alerts to when problems arise:

Host Set-up

For each server you want to monitor with TKmon, configure a host in TKmon:

Services Set-up

For each configured host you can monitor any services (such as Web servers, file servers, ...) as well as hardware components (such as RAID controllers) that are listed in the TKmon service checks.

To set up such a monitoring configure for the service or the respective component a service in TKmon. The Following example shows how to set up the monitoring of an VMware Host:

Note: Some service checks must be able to perform commands on the monitored server for the monitoring (for example to monitor CPU load, or for monitoring RAID controllers). For information about setting up such a service check on each server, see the articles Icinga NRPE Plugin and Install and configure NSClient++ under Windows.

Linux Host NRPE sample check

The configuration of a service check based on NRPE is similar to a local check.

Windows Host nsclient sample check

Unlike the linux host, the execution of the windows checks in TKmon is done by check_nt, not NRPE.

Service Status

In the Service Status you can check the current status (it will take a few minutes until the first check is performed after the new services are configured):

Install Updates

Updates can easily be applied from the TKmon web interface:
