[SOLVED] Display log files in UI

try this (change your folder structure and ip)

Script (shows the last 1000 events sorted by last event in first position)
script openhablogs.sh:

#!/bin/bash
tac /opt/oh18/logs/events.log | head -n 1000 > /opt/oh18/webapps/weblogs/events.log
tac /opt/oh18/logs/openhab.log | head -n 1000 > /opt/oh18/webapps/weblogs/openhab.log
date +"%d.%m.%Y %T"

item:

String st_copyLogs {exec="<[/opt/oh18/configurations/scripts/openhablogs.sh:60000:REGEX((.*?))]"}

sitemap:

Text label=“LogFiles” {
Text item=st_copyLogs label=“openhab.log [%s]” icon=“settings” {
Webview url=“xxxxx:8080/weblogs/openhab.log” height=20
}
Text item=st_copyLogs label=“events.log [%s]” icon=“settings” {
Webview url=“xxxxx:8080/weblogs/events.log” height=20
}

Hi,

I tried your solution @Tab_Daham
Bash script works fine. But how do you call the bash script? Is it triggered from openhab or by cron job or whatever?

from wiki: refresh in millisec.
> in: exec="<[<commandLine to execute>:<refreshintervalinmilliseconds>:(<transformationrule>)]"
should update every minute

Yeah, ok.
I was kind of blind.
And my problem was a permission issue.
Now everythinks works fine.
Thanks.

Does anyone has an idea how to adapt this to oh2/openhabian?

Where to find the logs?
Where to store the new log string?
Where to store script?

Another nice tool to display log files in openhab is frontail, just search for it in Examples of HABPanel Solutions - There is a screenshot as well as very basic “installation” instructions in that thread.

Nice work.

In openhab 2.x, the directions are different.

should it be ?

tac /var/log/openhab2/events.log | head -n 1000 > /etc/openhab2/html/events.log

I made the adaptations to OH2 but unsuccessful in sitemap view.

I would strongly suggest using frontail:

Purpose was to display the logs in a sitemap.
I am regularly using the frontail locally with the browser.

If you can give a little more info than “unsuccessful” it may help.

Exec binding v2 usage is very different to the v1 used in original post.

You can use a webview in the sitemap pointing to frontail.

Could you please give me a hint how to do that?

I have access to http://openhabianpi:9001/
and I can see on the top of the window:

tail -f /var/log/openhab2/openhab.log /var/log/openhab2/events.log

Sitemap webview
