DB2 Input Plugin

This repository contains a telegraf external plugin that collects metrics from DB2 RDBMS using performance monitor tables.

Installation

The plugin executes a python script to gather metrics. It requires proper installation of python3 with ibm_db extension module. The extension module might require extra environment variables, which must be set.

Setting up the appropriate privileges in DB2 This integration needs to execute queries on DB2 performance resources. Switch to the instance master user (e.g. DB2INST1) and run these commands in db2 CLI. You should start the database and attach to the database before running these, see test setup example.

db2 "update dbm cfg using HEALTH_MON on"
db2 "update dbm cfg using DFT_MON_STMT on"
db2 "update dbm cfg using DFT_MON_LOCK on"
db2 "update dbm cfg using DFT_MON_TABLE on"
db2 "update dbm cfg using DFT_MON_BUFPOOL on"

Validate whether the settings are correctly applied by running the following command:

db2 "get dbm cfg"

Among the configurations being output'ed, you should see the following settings:

Default database monitor switches  
  Buffer pool                         (DFT_MON_BUFPOOL) = ON  
  Lock                                   (DFT_MON_LOCK) = ON  
  Sort                                   (DFT_MON_SORT) = OFF  
  Statement                              (DFT_MON_STMT) = ON  
  Table                                 (DFT_MON_TABLE) = ON  
  Timestamp                         (DFT_MON_TIMESTAMP) = ON  
  Unit of work                            (DFT_MON_UOW) = OFF  
Monitor health of instance and databases   (HEALTH_MON) = ON

Clone the repository

git clone git@github.com:bonitoo-io/telegraf-input-db2.git

Modify telegraf configuration

[[inputs.exec]]
  commands = ["/path/to/telegraf-input-db2/db2_metrics.sh"]
  timeout = "60s"
  data_format = "influx"
#  ## Execution interval, can override default interval setting in [agent] section
#  interval = "60s"

Replace /path/to/telegraf-input-db2 with a directory of your clone. The db2_metrics.sh executes the python script and also ensures that DB2 user password is not printed in telegraf logs.

Modify /path/to/telegraf-input-db2/db2_metrics.sh

Modify hostname, port and database or your DB2 connection.
Modify username and password of your DB2 user.
