Config file

The easiest way to add/override configuration options is to modify the /etc/telem-gw.user.conf file

This config file is checked by telem-app by default without any additional command line arguments

Enable Periodical GI with predefined time interval

Add the follown lines to /etc/telem-gw.user.conf:

protocol.periodical-gi.use-interval=1
protocol.periodical-gi.offset=00:02:00

This will indicate to telem-app that it should do a Periodical GI every 2 minutes instead of every hour at 00:05:00.

If protocol.periodical-gi.offset is left out, then the default value of 00:05:00 is used.

If protocol.periodical-gi.use-interval is not set, then Periodical GI is done every hour at value assigned to protocol.periodical-gi.offset. E.g. in case of default 00:05:00 Periodical GI will be issued every hour at xx:05:00.

NB! This feature is available in firmware starting from 2017.09.05

Resetting

Use case: If for example by some invalid logic or fault in telem-app some AI values end up as NaN all the time. And restart or clear buffers does not help.

To fully remove all object info from telem-app in device SSH to the device, switch to root user and do the following steps:

$ /etc/init.d/S81telem stop
$ rm -f /var/local/telem/object_backup*
$ /etc/init.d/S81telem start

Note that rerunning telem app from command line like that renders upcoming console.log files unreadable for martem user. To alleviate the issue run the following as root:

$ chown martem:gws /var/log/telem/console*
