 Posted: Sat Mar 13, 2004 4:48 pm Post subject: I can't see graphs... |
 |
|
I have still problems... :oops:
First, my server runs with safe_mode ON. I changed safe_mode to OFF and netmrg ran. But when I want to see graphs, I can't see them...
I follow however the INSTALL file.
Must I compile PHP with the SNMP support ? with RRDTOOL support ?
Do Netmrg run with the safe_mode to On ? Which functions uses netMRG ? |

NetMRG does not require SNMP or RRDTOOL support to be built into your PHP, but it will not run in safe mode.
To debug a graph display problem, get the URL for a broken graph (it should contain 'get_graph.php'). Open the URL directly, appending "&debug=1" to the end. This should give you a text page with any problems with creating the graph. Please post the results.
Other people have had similar problems in the forum. Did any other posts help? |

I posted a new version of the phptimer script that doesn't use bcsub(). If you'd like to try it, it might make debugging this problem a bit easier.
You can download it here:

I had installed the new phptimer.php.
Now I have this with debug=1 when I want to see a graph :
| Code: |
/usr/bin/rrdtool graph - -s -108000 -e -360 --title "%dev_name% - Load Average" -w 575 -h 100 -b 1000 -v "run queue size" --imgformat PNG DEF:zero=/usr/local/var/lib/netmrg/rrd/zero.rrd:mon_25:AVERAGE DEF:data1=/usr/local/var/lib/netmrg/rrd/mon_5.rrd:mon_5:AVERAGE DEF:data1l=/usr/local/var/lib/netmrg/rrd/mon_5.rrd:mon_5:LAST DEF:data1m=/usr/local/var/lib/netmrg/rrd/mon_5.rrd:mon_5:MAX LINE2:data1#330066:"5 Minute " GPRINT:data1l:LAST:"Current\:%8.2lf %s" GPRINT:data1:AVERAGE:"Average\:%8.2lf %s" GPRINT:data1m:MAX:"Maximum\:%8.2lf %s" COMMENT:"\n" VRULE:1079391600#F00000

But I discovered a problem with the netmrg_cron.sh program. I have in the netmrg user mailbox messages from Cron. The message is :
| Code: |
/sur/local/bin/netmrg_cron.sh: 1079427601 - : syntax error: operand expected (error token is " ")
|
I have this message every 5 minutes when Cron run netmrg_cron.sh... |

Try just running netmrg-gatherer from cron instead of netmrg_cron.sh. All the shell script does is some cleanup if the gatherer dies for some reason, so running the gatherer directly is fine. You will probably want to redirect stdout, though (netmrg-cron > /dev/null).
BTW, what language is your Linux installed with? (echo $LANG)

When you run this command from the command line, what do you get?
| Code: |
| /usr/bin/rrdtool graph - -s -108000 -e -360 --title="Template Linux Box - System (UCD - CPU Percent User) (#1)" --imgformat PNG -g -w 575 -h 100 DEF:data1=/usr/local/var/lib/netmrg/rrd/mon_1.rrd:mon_1:AVERAGE AREA:data1#151590 |

These errors shouldn't cause any problems with viewing graphs, just the nav history will be broken. I develop with the latest PHP, so I don't get them. I'll get them fixed for the next version soon.
