If only a single database should be checked, use the --name parameter.
|
||||
The same applies to datafile-related modes.
|
||||
|
||||
Options specific to 'server::sql' mode:
|
||||
|
||||
--sqleval
|
||||
For results with multiple columns, this is the index (counting from
|
||||
1) of the column to evaluate with --warning and/or --critical. If
|
||||
this option is missing, the statement is assumed to return only a
|
||||
single column.
|
||||
--sqlname
|
||||
For results with multiple columns, this is the index (counting from
|
||||
1) of the column use as the output name (instead of --name2). If
|
||||
this option is missing, only the first row will be parsed.
|
||||
--sqlinfo
|
||||
For results with multiple columns, this is the index (counting from
|
||||
1) of a column to present as a detailed explanation.
|
||||
|
||||
In mode sql you can url-encode the statement so you will not have to mess
|
||||
around with special characters in your Nagios service definitions.
|
||||
Instead of
|
||||
--name="select count(*) from master..sysprocesses"
|
||||
|
||||
--name="select count(*) from master..sysprocesses"
|
||||
|
||||
you can say
|
||||
--name=select%20count%28%2A%29%20from%20master%2E%2Esysprocesses
|
||||
|
||||
--name=select%20count%28%2A%29%20from%20master%2E%2Esysprocesses
|
||||
|
||||
For your convenience you can call check_mssql_health with the --encode
|
||||
option and it will encode the standard input.
