New emonSD release: emonSD-30Oct18 (Raspbian Stretch Pi3B+ compatible) 🎉

That would be great, thanks. Please post a link to your mirror and I will add it to the download page.

I have just installed this version on a new SD Card, expanded the card to the full 16Gb and then restored my backup from the old card.

When I click emonpi update, the EmonCMS > Writer status then changes to: Daemon is not running, start it at ~/scripts/feedwriter.

Update log attached.

Thanks

Ian

Did you enable SSH? If so try

sudo systemctl status feedwriter.service

(and please post output) then

sudo systemctl start feedwriter.service

followed by the status.

I wonder if the backup is taking a setting, the update changes it, but the restore overwrites it. @glyn.hudson @TrystanLea

I note this line in the log

restarting service-runner
service-runner: no process found

use the commands above on service-runner to check it’s status.

On the admin page next to the Server Information there is a copy to clipboard button. Please press that then paste the result into a message - no other formatting required.

Ah Ok that branch is on the older feedwriter cron job (strangely came across this this week).

I think first check the cron job

crontab -l

Seems like crontab is default

# Edit this file to introduce tasks to be run by cron.
#     
# Each task to run has to be defined through a single line 
# indicating with different fields when the task will be run
# and what command to run for the task
# 
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').# 
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
# 
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
# 
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
# 
# For more information see the manual pages of crontab(5) and cron(8)
# 
# m h  dom mon dow   command

One last try then I’m out of ideas (not familiar with the older feedwriter service)…

The command in the script to restart it is

sudo /etc/init.d/feedwriter restart

That works, but reboot of the feedwriter.service worked too!

 sudo /etc/init.d/feedwriter restart
 Log is turned off
 Restarting feedwriter (feedwriter.php was not running...)

Still doesn’t explain/help as to why the feed writer is not restarted after emonpi update button is pressed.

I’ve raised it as an Issue.

Thanks

But also note what the actual emoncms buffer status is, it changes on the live server info, but the copy and paste version always says “loading…” so it’s effectively meaningless.

When the line below is showing, the buffer will continue increasing with a number of points to write.

Yes but I do not think that is fixable because of the way the Ajax call works. Just one to be lived with I suspect unless you could make a special call to the function and append the data at the end of the text buffer.

I wasn’t aware of that.
No one has commented on the issue I raised.

If it can’t be reported (copied) accurately, it shouldn’t included. So the best fix would be to remove it I guess, even if only temporarily. Simples!

I don’t think feedwriter was ever cron based… it changed from SystemV Init based startup to systemd based startup… You’re thinking of service-runner (which was initially cron and changed to systemd)

Not as simple as that I suspect. The output HTML is copied by using a class ID

within that copied area is the ajax call to update the number in the buffer

I suspect removing this section when copied might be well nigh impossible (but I’m no expert).

Ah yes - getting myself confused.

@borpin I had a similar problem when updating emonBase (using emonSD-30Oct18). After update noticed feeds was not updating, so tried sudo systemctl status service-runner.service and also sudo /etc/init.d/feedwriter restart. All seemed OK…

but still no feed updates.
But a reboot of the rPi fixed it.
