can someone help me to write correct grok filter for the pattern:
2021.08.27-17:15:02 INFO[172] - start running on dev2
i used this code below but this not show any logs on Kibana
else if [fields][hostgroup] == "sols_special_deactivation" { grok { match => { "message" => ['%{TIMESTAMP_ISO8601:time} %{LOGLEVEL:logLevel} %{GREEDYDATA:logMessage}'] } }}
