Monitoring

In order to monitor the recorder, whenever an MQTT message is received, the recorder will add an epoch timestamp and the last received topic a Redis key (if configured) or a file otherwise. The Redis key looks like this:

redis 127.0.0.1:6379> hgetall ot-recorder-monitor
1) "time"
2) "1439738692"
3) "topic"
4) "owntracks/jjolie/ipad"

The monitor file is located relative to STORE and contains a single line, the epoch timestamp at the moment of message reception and the topic separated from eachother by a single space:

1439738692 owntracks/jjolie/ipad
