2) ntopng.service status records a lot of message about rm :
Jun 23 15:07:40 myserver.mydomain.tld ntopng[4629]: /bin/rm: missing operand
Jun 23 15:07:40 myserver.mydomain.tld ntopng[4629]: Try '/bin/rm --help' for
more information.
=> I noticed that the exec script searches only for "-G" option to find the pid
file but I set the "--pid" option. So, I modified the script this way :
#PID_FILE=$(cat /etc/ntopng/ntopng.conf | grep '\-G='|cut -d '=' -f 2)
PID_FILE=$(cat /etc/ntopng/ntopng.conf | grep -E "\-G=|--pid"|cut -d '=' -f 2)
=> See /etc/systemd/scripts/ntopng for this part.
3) last issue, not resolved for now, if I reboot the server, ntopng starts with
errors. The web UI is up but no data is available. If I restart the ntop
service, everything goes OK. :
Jun 23 15:00:23 myserver.mydomain.tld ntopng[3154]: [src/Redis.cpp:108] ERROR:
LOADING Redis is loading the dataset in memory
Jun 23 15:00:23 myserver.mydomain.tld ntopng[3154]: [src/Redis.cpp:1297] ERROR:

Jun 23 15:00:23 myserver.mydomain.tld ntopng[3154]: [src/Redis.cpp:125] ERROR:

Have you tried to reset Redis with redis-cli flushall?
I just flushed the cache and reboot. Everything goes OK at restart.
So I guess that after a limit, redis takes too much time to read its cache.
ntopng should wait for a "ready" message from redis. Is it true ? So I just need
to wait if the issue comes back ?
There was some Redis keys rework between 1.2 and 2.0, which probably caused the
issue until you flushed the cache. Should you experience any other issue please
do not hesitate to report it.
Thanks,
Arianna
=> so I tried to modify the systemd unit ntopng.service to set it to start after
redis.service.
In file /etc/systemd/system/ntopng.service, add "redis.service" to the "After"
line :
That is a great idea, thanks for suggesting it.
You're welcome.
