4 | 1 | chin-yeh | |
5 | A service should be grouped under a specify service group to ease the configuration tasks. |

7 | 1 | chin-yeh | *[Important]* Prepare the following information before begin: |
8 | 12 | chin-yeh | * *host name* - the host name of the host to be assigned; the particular host name must exists in the @/usr/local/nagios/etc/ecosway/hosts/hosts.cfg@ and @/usr/local/nagios/etc/jmx4perl/servers.cfg@ |
9 | 7 | chin-yeh | * *service group* - the group name of the service to be monitored |
10 | 1 | chin-yeh | |
11 | 12 | chin-yeh | |
12 | 3 | chin-yeh | List of available services: |
13 | 6 | chin-yeh | * [[Assign Service to Host#Assign-DB2-service|DB2]] |
14 | * [[Assign Service to Host#Assign-Third-Party-Service|Third Party Service]] |

19 | h2. Assign DB2 service |
||
20 | |||
21 | 7 | chin-yeh | Assumes that the target DB2 host has a @nagios@ user and the user has the monitor related privileges assigned. |
22 | |||
23 | The currently available commands for DB2 service are: |
||
24 | * *db2_connect_cmd* - check the time taken to establish connection to DB2 |
||
25 | |||
26 | You may need the following additional information: |
||
27 | * *database name* - the name of the database to be monitored |
||
28 | * *warning threshold* - the warning threshold of this service in seconds unit, e.g. 3 for seconds |
||
29 | * *critical threshold* - the critical threshold of this service in seconds unit, e.g. 5 for seconds |
||
