these are my config at sensu side :
{
"logstash": {
"output": "udp",
"server": "localhost",
"port": 5000,
"list": "logstash",
"type": "sensu-logstash",
"custom": {
"@metadata": {
"type": "sensu logstash handler",
"beat": "sensu"
}
}
},
"handlers": {
"logstash": {
"command": "/etc/sensu/handlers/handler-logstash.rb",
"type": "pipe"
}
}
}

config file at logstash.conf
input {
tcp {
port => 5000
type => "company-tcp"
codec => "json"
}
udp {
port => 5000
type => "company-udp"
codec => "json"
}
}

filter {

}

output {
if ("METRICS" in [tags]) {
elasticsearch {
hosts => ["elasticsearch"]
index => "metrics-%{+YYYY.MM.dd}"
}
} else {
elasticsearch {
hosts => ["elasticsearch"]
index => "logstash-%{+YYYY.MM.dd}"
}
}
stdout {
codec => rubydebug
}
}

Sensu is executing my checks but on logstash there are no logs from sensu!!!
thanks in advance


(Magnus Bäck) #6

Have you established that Sensu actually tries to connect to Logstash? Have you looked in the Logstash logs to see if Logstash is having any problems processing the events?
