[SOLVED] summary GRAPH

[dav.ge]

Hi,
proxmox 5.3.-8
on 1 node summary graph doesn't show any graph (cpu usage, server load, memory usage etc.).
I try to use:

rrdcached -P FLUSHALL

but reports

rrdcached: can't create pid file '/var/run/rrdcached.pid' (File exists)
FATAL: Another rrdcached daemon is running?? (pid 1779)
rrdcached: daemonize failed, exiting.

so i delete /rrdcached.pid' and execute again rrdcached -P FLUSHALL.
Restarted node, cleaned browser cache but graph still not appear...
Any solution ?

 

[dcsapak]

does

pvesh get /nodes/NODEID/rrddata -timeframe hour --output-format json-pretty

return anything?

RRD error: rrdcached: rrd_fetch_r failed: opening '/var/lib/rrdcached/db/pve2-node/NODEID': No such file or directory

 

[dcsapak]

you have to replace 'NODEID' with your nodename

 

[dav.ge]

root@pm1-i1:/var/run# pvesh get /pm1-i1/rrddata -timeframe hour --output-format json-pretty
Unknown option: timeframe
400 unable to parse option
pvesh get <api_path> [OPTIONS] [FORMAT_OPTIONS]

 

[dcsapak]

please do

pvesh get /nodes/pm1-i1/rrddata -timeframe hour --output-format json-pretty

[dcsapak]

ok the data is there, did you maybe change the timeframe in the upper right corner to a too high one?

 

[dav.ge]

OK! changing timeframe graph comes back . Thank you very much. Now seems to be ok on all time frame ...

rrdcached -P FLUSHALL ( please use small letter p)

 

[Andres Vargas Duarte]

Hello everyone,

It can be fixed by deleting the folders or to prevent better, rename the folders that are inside "/var/lib/rrdcached/db"

Folders:
pve2-node
pve2-storage
pve2-vm

NOTE: all the counters will be reset and the previous graphs will be lost, if the failure is only for the "Node" they can only try with the "pve2-node" folder, if not all.

No need to reboot.

Greetings.
