Now you can use regexes in {{Joined column}}s. If multiple entries are found the first one of the sorted entries will be used.

These regexes can be combined with macros in inventory based views and are evaluated {{AFTER}} the macro replacements. These macros don't need to be escaped, all other special characters have to be escaped: {{ORA $SID$\.SYSTEM Tablespace}}

Example:

  • Choose {{Oracle instances}} as the data source
  • Choose {{SID}} with {{$SID$}} below macros
  • Now you can connect {{Services: Summary}} of the services {{ORA $SID$.(SYSAUX|TEMP) Tablespace}} below {{Joined column}}

Note:

These regexes are basically case sensitive. If you need case insensitive regexes you have to add the global flag {{(?i)}} at the beginning of this regex.

Example:

  • From the data source {{Oracle instances}} we get the SIDs in upper case format
  • Items in filesystem service description are in lower case format
  • Use the regex {{(?i)Filesystem /path/to/$SID$}} below {{Joined services}} in order to join the related service column
