Check_MK Werk 7095: oracle_sql: New check for monitoring custom SQLs

ID: 7095 Title: oracle_sql: New check for monitoring custom SQLs Component: Checks & agents Level: 1 Class: New feature Version: 1.6.0i1 The mk_oracle allows the execution of parametrizable custom SQLs. Note that the following configuration is not bakeable. First of all you have to register sections and configure their options. This can be done in the {{mk_oracle.cfg}} via <code> SQLS_SECTIONS=sec_a,... sec_a () { #OPTIONS } </code> In general there are two types of check plugins which handle the output of the custom SQLs: <ol> <li>{{oracle_sql}} for generic custom SQLs</li> <li>own check plugins if {{SQLS_SECTION_NAME}} is used (see below)</li> </ol> The following configuration variables can be stated globally or locally (within a section definition; this overwrites the global variable). <code> SQLS_SIDS=sid1,sid2,... (comma separated) SQLS_DIR=/path/to/dir (no trailing '/') SQLS_SQL=name.sql (the SQL name which must exist in SQLS_DIR) SQLS_PARAMETERS=params (parameters as string, double quotes are removed) SQLS_MAX_CACHE_AGE=X (x in seconds) SQLS_SECTION_NAME=sec_name (optional, for own check plugins; if not stated, 'oracle_sql' is used; generic check plugin) SQLS_SECTION_SEP=separator (optional; only useful if SQLS_SECTION_NAME is stated; ASCII code, eg. '58' means ':') </code> <ul> <li>{{SQLS_SIDS}: For which SIDs the SQL is executed.</li> <li>{{SQLS_DIR}}: The folder of the SQLs.</li> <li>{{SQLS_SQL}}: The SQL name within SQLS_DIR.</li> <li>{{SQLS_PARAMETERS}}: Declare parameters if needed. Mostly they are declare within double quotes. In this case you have to escape them if yu need them as characters within the parameters.</li> <li>{{SQLS_MAX_CACHE_AGE}}: How long the cached data is recent enough.</li> <li>{{SQLS_SECTION_NAME}}: The output of the SQL is stored below this section. That means you have to build your own check plugin.</li> <li>{{SQLS_SECTION_SEP}}: At which character the output is separated.</li> </ul> If the generic {{oracle_sql}} section header is used then the item within the custom SQL service can be influenced by {{SQLS_ITEM_NAME}}: <code> SQLS_ITEM_NAME=item_name (optional, if not stated, sql name is used) </code> Otherwise the SQL name {{SQLS_SQL}} is used.
