Uptime graph shows broken link image, other graphs are fine

[sarakline]

We are running Cacti .8.7e and all of our graphs look great except for the uptime graph. It displays a broken image tile instead of a graph. Any thoughts? has anyone else ran into this? We are running CentOS 5.2.

[noname]

1) What graph template are you using for the uptime graph?
2) What OID is specified in the data template? Please perform snmpget with that OID to target host.

[sarakline]

1. ucd15 uptime
2. .1.3.6.1.2.1.25.1.1.0, when we performed snmpget on the host we got a correct return of 24 days, 5 hrs and 10 minutes.
Thanks for helping!

>> ucd15 uptime

Is this?

What do you see when you did as follows?

a) Graph Management -> "xxxx - Uptime" -> "*Turn On Graph Debug Mode."
b) Data Sources -> "xxxx - ucd_hrSystemUptime" -> "*Turn On Data Source Debug Mode."

[sarakline]

We get a) ERROR: the RRD does not contain an RRA matching the chosen CF

b) Did not return an error, just this:

This datasource was created as follows. It contains "AVERAGE" and "MAX" CF.

/usr/bin/rrdtool create \
/var/www/cacti/rra/SYSNAME_ucd_hrsystemuptime_1727.rrd \
--step 300 \
DS:ucd_hrSystemUptime:GAUGE:600:0:U \

RRA:MAX:0.5:6:700 \

..but graph template requires "LAST" CF for drawing graph.

/usr/bin/rrdtool graph - \

You can add that CF manually.
(See also: http://forums.cacti.net/viewtopic.php?p=201196#p201196)

1) Data Sources -> RRAs
2) Add "LAST" CF for each RRAs


3) On server, delete the RRD file of this issue if existed (SYSNAME_ucd_hrsystemuptime_1727.rrd)
4) Wait until next polling, then check whether if RRD file with same name have been created
5) If ok, wait for 1-2 polling (5-10 minutes) further, then check graph

NOTICE:
After adding new CF...

• It affects datasources (RRD files) newly created from this time
• It doesn't affect existing datasources
• New RRD file is about 50 percent larger than the former one in size (2 CFs -> 3 CFs)

EDIT: supplemented descriptions (in purple color)

BTW,

this template "UNIX Template Set for Cacti: HP-UX, Solaris, Linux" will replace some existing graph templates & data queries.

• Graph Templates
• "Interface - Traffic (bits/sec)" -> "ucd 00 Lan"
• "Host MIB - Available Disk Space" -> "ucd 90 Filesystems"

• Data Queries
• "SNMP - Interface Statistics" -> "ucd 00 Lan"
• "SNMP - Get Mounted Partitions" -> "ucd 10 fs"

It uses the same hash code as existing one -- probably created by modifying default template.
Please use with attention (especially when you want to delete that template).

Where would the rrd file be stored at? I am seeing where I can delete the data source but I don't think that is what you are wanting me to do. Everything would have been installed with defaults so the path should be default. Do I delete the rrd file within the software or out at the terminal? If so what is the path?

[noname]

Ah, sorry. I supplemented some descriptions to the above post.

You should delete "/var/www/cacti/rra/SYSNAME_ucd_hrsystemuptime_1727.rrd" if it existed.
Alternatively, delete the existing graph settings (broken) and datasource settings (RRD file isn't created actually) in Cacti GUI, then re-create it.

That has fixed 4 of the five. The four that are fixed are the ones where I just removed the rrd file. The one that is not working is from earlier troubleshooting efforts. The data source was deleted then recreated. I have removed its rrd files but the graph will still not come up. Did something possibly get messed up when the data source was deleted?

[sarakline]

I figured out what happened. When the data source was recreated, it was no longer linked to the template as the old one had been. All I had to do was add it back in and everything is working great. Thank you so much for your help!
