To generate a bar graph for the given scenario

I have a log from which i need to extract the state field and generate a bar graph for the state transitions that the logs have gone through for a given NexthopId. Please help me with this scenario.

LOGS:
2020-03-06 09:36:50.775744749 re0:ndp:25786 lltp_debug message = "NDP-DBG:NC_FSM_HANDLER:1634:: state 4, event 0, NexthopId 44000"

Here is my logstash config file:

input {

file {

start_position => "beginning"

sincedb_path => "/dev/null"

}

}

filter {
grok

"message" => ["%{TIMESTAMP_ISO8601:timestamp} %{WORD:node}:%{WORD:program}:%{INT:pid} %{WORD:tracetype}.*%{mssg} "%{GREEDYDATA:Message}""]
"Message" => ["NexthopId %{WORD:next_hop_id}", "state %{WORD:state}", "event %{WORD:event}"]
}
}
mutate
{
remove_field => [ "message" ]
}

translate {
field => "[state]"
destination => "[state_name]"
dictionary => {
"0" => "Unknown"
"1" => "No state"

}

}
output {

}

Does that ingest script work? What problems are you having?

Hi,

The script works fine. Now i have a scenario where i must generate a graph that shows the state transitions for a given nexthop Id.

I went through kibana visualisation, but i am not able to figure out how to display state transtions.
Can you please help me out?

How does a document look like? It's pretty hard to figure that out from a ingest script.
Normally you can display the latest value of a document and do a split by term on NexthopId.
