Check_MK Werk 7083: Apache sends out minimal information about the running software and platform to HTTP clients

by Lars Michelsen

ID: 7083 Title: Apache sends out minimal information about the running software and platform to HTTP clients Component: Site Management Level: 1 Class: Security fix Version: 1.6.0i1 The site apache reports information about the running software and platform to the HTTP clients with each HTTP response using the "Server" HTTP header. It is common practice to minmize this information using the apache configuration option "ServerTokens Prod" which we do now for the site apache by default. We don't modify this setting for the system wide apache. You'll have to configure the system apache on your own in case you want to configure it to work in the same way.

Check_MK Werk 7141: mk_docker: Inventorize RepoTags and RepoDigests unprocessed

by Moritz Kiemer

ID: 7141 Title: mk_docker: Inventorize RepoTags and RepoDigests unprocessed Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously, the last RepoTag was picked, and inventorized as 'Repository' and 'Tag' separately. This was somewhat arbitrary, so we now inventorize all RepoTags and RepoDigests without any further interpretation.

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

by Simon Betz

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.

Check_MK Werk 7034: mk_logwatch: Parse files only

by Florian Kromer

ID: 7034 Title: mk_logwatch: Parse files only Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Previously the configuration of logfile patterns (like e.g. /var/log/*) which matched directories lead to errors during parsing of logfiles because directories have not been skipped. This werk adds filtering of directories and limiting of parsing to files (inlcuding soft linked and hard linked ones). CMK-1633

Check_MK Werk 6869: Fixed all crashes in Windows Agent caused by UTF-16 to UTF-8 conversion

by Sergey Kipnis

ID: 6869 Title: Fixed all crashes in Windows Agent caused by UTF-16 to UTF-8 conversion Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 Some Windows checks may produce invalid UTF-16 symbols or symbols which are difficult to convert into UTF-8 using standard library. As a result the Agent may crash with exception 'range_error' during 'to_bytes' call. Now in such cases the Agent uses native Win32 API call avoiding the crash. Provided output from above mentioned Win32 API call conforms to the UTF-8 standard.

Check_MK Werk 7081: Reworked "Distributed Monitoring" page

by Lars Michelsen

ID: 7081 Title: Reworked "Distributed Monitoring" page Component: WATO Level: 2 Class: New feature Version: 1.6.0i1 The "Distributed Monitoring" pages have been reworked to make it easier to manage multiple Check_MK site connections. The list page is now showing less site configuration details. Instead of these columns status columns have been added to visualize whether or not your site connections can currently be used. One column shows the current status of the Livestatus connection, which is needed by the GUI to gather the monitoring status from the site. In case your livestatus connection is not configured properly, you may have a look at the status and hover the icon for more information about the reason. One possible reason for a non functional Livestatus connection may be a TLS connection issue (if you use encrypted Livestatus). You can use this site to inspect the remote site certificate and establish a trust with this certificate to allow the GUI to connect with that site. The replication status column tells you whether or not the configuration replication connection is working.

by Lars Michelsen

ID: 7082 Title: Fixed "omd create" when fstab has 0 bytes Component: Site Management Level: 1 Class: Bug fix Version: 1.6.0i1 The "omd create" command failed with a "IndexError: string index out of range" in case a /etc/fstab file existed but was empty. While regular systems most likely have entries in there, this can often happen for containers.
