Adrien Vergé 44f18db80d Fix YAML errors reported by yamllint
Especially the config for ArcSight, that was invalid:

    tools/config/arcsight.yml
      89:5      error    duplication of key "product" in mapping  (key-duplicates)
      90:5      error    duplication of key "conditions" in mapping  (key-duplicates)

    rules/windows/builtin/win_susp_commands_recon_activity.yml
      10:9      error    too many spaces after colon  (colons)
2019-01-10 09:51:39 +01:00
Thomas Patzke 9f56b9e99b Output all YAML documents if one changed
Some Sigma rule collections contain YAML documents that reduce to almost
nothing because they only contain EventID definitions. Previous behavior
would filter the part with the remaining selection.

sisecbe c2eb87133d Distinct count in aggragation function
Added dc() instead of count() when group-by field is present. Because count() doesn't do a distinct count in Splunk. Must be the dc() function instead.
