I am working through a Udemy course to familiarize myself with Elasticsearch but I've ran into a wall when applying it to our current environment when it comes to Logstash. I am trying to send data from Cisco syslog but when I view it when running in the cli the result is grokparsefailure. …

[image] jabberwalker: match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp} %{GREEDYDATA:syslog_message}" } That has a space after the timestamp, your message has a colon there. BTW, just starting with one field and then expanding the pattern one or two fields at a time is a good idea…
