The SQL input package allows you to execute custom queries against an SQL database and store the results in Elasticsearch.
This input package supports the below listed databases:
- MySQL
- Oracle
- Microsoft SQL
- PostgreSQL
Configuration Options for the User:
Hosts:
The host configuration should be specified from where the metrics are to be fetched. It varies depending upon the driver you are running
MySQL:
The supported configuration takes this form
<user>:<password>@tcp(<host>:<port>)/
Example of supported configuration is as below:
root:root@tcp(localhost:3306)/
Oracle:
The following two types of host configurations are supported:
-
Old style host configuration :
a.
hosts: ["user/pass@0.0.0.0:1521/ORCLPDB1.localdomain"]b.
hosts: ["user/password@0.0.0.0:1521/ORCLPDB1.localdomain as sysdba"] -
DSN host configuration:
a.
hosts: ['user="user" password="pass" connectString="0.0.0.0:1521/ORCLPDB1.localdomain"']b.
hosts: ['user="user" password="password" connectString="host:port/service_name" sysdba=true']
MSSQL:
The supported configuration takes this form
sqlserver://<user>:<password>@<host>
Example of supported configurations is as below:
sqlserver://root:test@localhost
PostgreSQL:
The supported configuration takes this form
postgres://<user>:<password>@<connection_string>
Example of supported configuration is as below:
postgres://postgres:postgres@localhost:5432/stuff?sslmode=disable
Note: If the password contains the backslash (\) character, it must be escaped with a backslash. For example, if the password is my\_password, it should be written as my\\_password.
Driver
Specify the driver for which you want to run the queries. Below are the supported drivers:
- mysql
- oracle
- mssql
- postgres
SQL_Queries
Receives the list of queries to execute. query and response_format is repeated to get multiple query inputs.
Eg:
sql_queries:
-
query: SHOW GLOBAL STATUS LIKE 'Innodb_system%'
response_format: variables
response_format: This can be either variables or table
variables: Expects a two-column table that looks like a key/value result. The left column is considered a key and the right column the value. This mode generates a single event on each fetch operation.
table: Expects any number of columns. This mode generates a single event for each row.
For more examples of response format pelase refer here
Merge Results
Merge multiple queries into a single event.
Multiple queries will create multiple events, one for each query. It may be preferable to create a single event by combining the metrics together in a single event.
This feature can be enabled using the merge_results config.
merge_results can merge queries having response format as "variable".
However, for queries with a response format as "table", a merge is possible only if each table query produces a single row.
For example, if we have 2 queries as below for PostgreSQL:
sql_queries:
-
query: "SELECT blks_hit,blks_read FROM pg_stat_database LIMIT 1;" response_format: table
-
query: "SELECT checkpoints_timed,checkpoints_req FROM pg_stat_bgwriter;" response_format: table
The merge_results feature will create a combined event, where blks_hit, blks_read, checkpoints_timed and checkpoints_req are part of the same event.
