cacti does not show graphs

[zapeador]

Hello, reinstall an operating system and some graphs do not work for me and others do, especially one of the ones I need is this one and it does not show data
I show you here the debug in case anyone sees an error

Code: Select all

Comando RRDtool:
/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start='-86400' \
--end='-60' \

--base=1000 \
--height=200 \

[zapeador]

any idea where to look

[macan]

is rrd file updated? Try this:
rrdtool dump /var/www/html/cacti-1.2.16/rra/titan_5_mem_total_4916.rrd
Are there actual data?

yes, there is real data, any risk in that command?

execute the command but it does not make any changes, the graphs from the web are still empty

Sorry for the late reply but I was sick and couldn't check my email

here I pass the output of the command, after the last lines everything is repeated the same so I have cut it

You haven't actual data. Try to enable debug device and post part of cacti log with debug

Sorry for my lack of knowledge, how do I activate the debug?

[macan]

management->device->choose device->right upper corner

[zapeador]

I already activated so in the graphical interface but it seems to me that the same thing comes out...

[macan]

Debug information are stored in log. We need relevant part of log.

[zapeador]

Debug information are stored in log. We need relevant part of log.

And what can I look for to be relevant information? because in the log found in /var/www/html/cacti/log in the file cacti.log cat cacti.log | grep titan which is from the machine that I want information but it does not give me results

Any suggestion to provide more information?

Thanks

[macan]

Your device has any ID, https:// cacti_url/host.php?action=edit&id=44

You can search in log:
grep "Device\[44\]" /var/www/html/cacti/log

Past here debug messages from one poller cycle
