Downtime visualization in Kibana from logs

Elastic Stack Kibana
1

Hi,

is it possible to create visualizatoin in Kibana from log messages for downtime?
Example:
at 18:01 i recieve syslog that server is down
at 18:05 i recieve syslog that server is up.

Would it be possible in Visualization create graph which will show the downtime?

Thanks

You can assign a value to each log message using something like a scripted field if they follow some kind of pattern and then do a histogram to chart the values of those fields per the interval you receive the log messages(if you receive messages consistently that say the status of the server).
if not, then I just recommend setting up Heartbeat and then you have a specific app in Kibana (Uptime) that will do everything for you and where you can easily setup alerts.
