Log to syslog from lua script

[Haraldinho 0]

Dear community,

 

Has anybody figured out how to send log statements to a syslog server from lua scripts? I want to do a more systematic logging so I can figure out better when scripts have failed and why. Doing print() statements is not a structural solution.

I've got the same question. I would like to see some better logging capability than just having the output in the output window. There is no easy way to see what the state of the HC2 is when you have to click around to every scene to see if there have been any errors.

its not quite the same but I use a a small function in each scene/vd along with a predefined global variable to append data to MY log aling with a rough date and time stamp

i can then look back at the log or add extra logging to a scene/vd is its something new I'm working on. This approach has allowed me to see how a couple of scenes interact.

 

this is the function I use - its a bit rough but works

In the end I went for a slightly different take.

 

I've got two python scripts, one for pulling log messages out of <fibarohost>/api/scenes/<scene>/debugMessages and the other for pulling stats from devices.

I stick the logs and the metrics into a container running elasticsearch and then read that from a container running kibana.

Nice, @Tor Magnus! I have done something very similar, but using influxdb and grafana. See also my post below.

Cool @ReneNL, great minds think alike. I was looking at influxdb/grafana at first myself as I'd used it before, however as I wanted debug messages as well it was a bit of a hassle. I might still hook up grafana to elasticsearch, however a greater concern for me at the moment seems to be the unreliability of data logging from the Aeotec 6in1...
