Hi everyone, We just installed a new instance of Ganglia on Rocky OS 8.4. Everything works well except the stacked graph doesn't show up. I searched this forum and found a few similar cases. For example, Janet reported this issue in 2021, but in a CentOS 7 system. Vladimir provided some solution but didn't work in Rocky 8 system. I also following some instructions for debug. Copied the address of the stacked graph and appended '&debug=5', which produced a command like this. /usr/bin/rrdtool graph - -E --start \&\#039\;-3600s\&\#039\; --end \&\#039\;N\&\#039\; --width 700 --height 300 --title \&\#039\; aggregated load_one last hour\&\#039\; --upper-limit \&\#039\;0\&\#039\; --lower-limit \&\#039\;0\&\#039\; CDEF:total=0 CDEF:mean=total,0,/ CDEF:last_total=total,POP,0 CDEF:last_mean=last_total,0,/ COMMENT:'\j' GPRINT:'total':AVERAGE:'Avg Total\: %5.2lf' GPRINT:'last_total':LAST:'Current Total\: %5.2lf\c' GPRINT:'mean':AVERAGE:'Avg Average\: %5.2lf' GPRINT:'last_mean':AVERAGE:'Current Average\: %5.2lf\c'
When I ran this command in the machine, I got this result. ERROR: start time: unparsable time: &'-3600s' Does anyone know what can cause this? It seems a bug in stacked.php or relative program, but I'm not familiar with this and cannot figure it out. By the way, we have been using Ganglia for a long time. It works perfectly in CentOS 7. But we have to upgrade CentOS 7 since it's near end-of-life. Any help would be appreciated. Zhongdong
