OP5 Monitor - How to install Bischeck – Support - ITRS Group

Disclamer

This is an unsupported plugin. More information about the Bischeck plugin can be found at the bischeck github page or at the bischeck.org.

Prerequisites

This guide will help you install Bischeck for OP5 Monitor and requires you have basic Linux skills.

To be able to use Bischeck, Nagios Service Check Acceptor (NSCA) also needs to be configured.

For up-to-date instructions regarding the installation of Bischeck, refer to the documentation on the official Bischeck website.

For Bischeck to correctly function, you will need to make configuration changes.

In file /etc/nsca.cfg change:
```
decryption_method=14
```
to
```
decryption_method=3
```
There are only 3 supported methods with Bischeck, 0,1 and 3. 0 = no encryption, 1 = XOR and 3 = 3DES. If using decryption_method=3 causes performance issues, lower the decryption method to 0 or 1.
Either change the password parameter in the same file to something else or copy the on already set.
Restart the NSCA service
```
service nsca restart
```
Open up the file /opt/monitor/op5/bischeck/etc/servers.xml and edit the following two properties, here we assume that you are using encryption method 3 and has not changed the default password:
<property>

  <key>encryptionMode</key>

  <value>TRIPLE_DES</value>

</property>



<property>

<key>password</key>

<value>OP5_Monitor_R3Mote_Probe</value>

</property>
Restart bischeckd service
```
service bischeckd restart
```
