V2.9a fixes the noise graph plotting problem

[Rob]

To install 2.9a and get noise graphing working:

1) Stop WD:                             "./wsprdaemon.sh -z"
2) clean your signal_level logs:  "rm -rf signal_levels/"  (sorry, but you WILL loose your logs)
3) get 2.9a:                              "git pull"
4) start WD:                              "./wsprdaemon.sh -z"

I am not aware of any other bugs in 2.9 which need to be fixed

Typo?
4) start WD:                              "./wsprdaemon.sh -a"

Cheers

Yes, a typo:  'wd -a' starts WD
thanks

I have installed V2.9a now...
I can see my noise plots created: http://wsprdaemon.org/graphs/ON5KQ/

However how can I see the graphs in the Grafana Dashboard ? It says "no data"...
https://grafana.int8.com/d/3dcOdAmWk/calibrated-noise-dashboard?orgId=1&from=now-24h&to=now&refresh=1m&var-site=ON5KQ&var-receiver=All&var-band=All

Do I need to build the dashboard myself following the guide from Gwyn on the website ?
I have installed Grafana now and start learning.... looooooooong way to go, for an IT-Idiot like me...

The grafana.int8.com site is no longer in use.
Gwyn has recently updated the TS and Grafana documents to show how to use the new TS database.
I think there is a 'open' user which you can use on the new server, but Gwyn is really in charge of this aspect of WD.

In understand - his tutorials on Grafana are excellent - my learning curve is however too slow (old style..)

One thing I always have problems with is that the wsprdaemon.log file gets bombed with this since I started using WD with version 2.5a

Traceback (most recent call last):
  File "/tmp/wsprdaemon/noise_plot.py", line 69, in <module>
    noise_vals = genfromtxt(csv_file_path, delimiter=',')[:,1:]  
IndexError: too many indices for array
mv: cannot stat '/tmp/wsprdaemon/wd_tmp.png': No such file or directory

I don't understand the code at all, but I guess, it shouldn't be there... I get it all the time...
I think I better re-install the whole system ?!
But even that I have done several times, without succes...

Any advice ?
What does it mean ?

Have now appox 20m of wire connected to a single kiwi, just to do something...

You can ignore those error lines if they appear only once at WD startup.

I'll put fixing that on the TODO: list of 2.9x

I just checked in V2.9b with fixes to suppress those spurious startup errors  along with some other low risk error checking.  Users of 2.9a need not upgrade to 2.9b.
