FreePBX statistics display window empty

I have installed FreePBX version 16.0.14 using Asterisk version “16.16.1~dfsg-1+deb11u1”; no upgrade, just a plain vanilla installation running since 2 weeks.

Though when opening the FreePBX web interface using either the Edge or the Firefox browser the displet is always empty.

I select for example the “CPU-Week” category, which shows as depicted below an empty statistics displet window:


However, no data :slightly_frowning_face:

I then click on the refresh button on the top left corner, and am getting the following displet contents:


It is showing some straight lines for the Asterisk category, albeit I in my previous step I have chosen the “CPU” category :slightly_frowning_face:

Above can be reproduced for any chosen category on different web browsers :anguished:

Here the “sudo -u asterisk crontab -l” output, as I have seen this kind of request in other posts:

* * * * * [ -e /usr/sbin/fwconsole ] && sleep $((RANDOM\%30)) && /usr/sbin/fwconsole job --run --quiet 2>&1 > /dev/null
* 5 * * * /usr/sbin/fwconsole util cleanplaybackcache -q
24 6 * * 6 [ -e /usr/sbin/fwconsole ] && /usr/sbin/fwconsole ma listonline --sendemail -q > /dev/null 2>&1

Full info would be cool… looks like you are using some derivative of debian. There is a chance you are missing a library or a command is different. This stuff is tested on the SNG7 which is an EL derivative. A lot of things do “just work” in debian because there is a strong presence of debian users in the community including those that use builds on the raspi.

My guess would be a missing library.

It is the standard Asterisk package that comes with Debian 11 Bullseye. Its latest status can be consulted under the respective Debian Package Portal.

The latest stable version is indeed “16.16.1~dfsg-1+deb11u1”. The installation can be easily accomplished with the “How to Install Asterisk VoIP Server on Debian 11” guide.

Nothing wild, have done this many times in the past in conjunction with previous versions of FreePBX and Asterisk under Debian 9 Stretch.

I do not see any problems with the Asterisk installation itself.

For me it is merely a problem with the web representation of statistics gathered and (lack of displaying) on the respective displet window of the FreePBX application.

I’ve seen a lot of my FreePBX15 and 16 distro systems show the same behavior. Some time later (hours or a day) after the system has been running a while the data will start to appear. System reboots will cause the “hour” stats to be blank again sometimes…

It always fixed itself after a period of time so I never really bothered complaining about it.

Thus, is this behaviour expected to be normal?

doesn’t seem to affect functionality beyond the dashboard. Not sure if I’d call it normal. that’s a deeper question for a developer.

The lack of drawing graphs on the statistics displet windows may not affect the underlying operational behaviour of FreePBX.

However, there is simply no availability of statistics for more then 2 months now, despite having updated the framework to 16.0.17.

Is ‘Settings’ → ‘Advanced Settings’ → ‘Dashboard Module’ → ‘Disable collection of system statistics’ set to ‘No’?

Thank you for the pointer: I have toggled the switch for the “Settings / Advanced Settings / Dashboard Module / Disable collection of system statistics” twice back to “No” and am getting now the statistics as depicted with:
