Graph title is showing|query_ifDescr|/|query_ifIndex|

[floattent]

Hi all,

I'm using cacti-0.8.8a on a Linux machine and using the standard "interface.xml" file and the standard "Interface - Traffic (bytes/sec)" graph template to collect some traffic stats on a Ciena 61xx device.

But the graph title is not showing correctly as it is supposed to be. Please see the screen shot attached. It didn't parse the " |query_ifDescr|/|query_ifIndex|" value. snmpwalk on the "ifDescr" & "ifIndex" had no problems.

IF-MIB::ifDescr.1 = STRING: Port_SDH-4-1-6-1
IF-MIB::ifDescr.2 = STRING: Port_SDH-4-1-6-2
IF-MIB::ifDescr.3 = STRING:
IF-MIB::ifDescr.4 = STRING:
IF-MIB::ifDescr.5 = STRING: Port_Eth-100-1-5-1
IF-MIB::ifDescr.6 = STRING: Port_Eth-100-1-5-2
IF-MIB::ifDescr.7 = STRING: Port_Eth-100-1-5-3
IF-MIB::ifDescr.8 = STRING: Port_Eth-100-1-5-4

IF-MIB::ifIndex.1 = INTEGER: 106001
IF-MIB::ifIndex.2 = INTEGER: 106002
IF-MIB::ifIndex.3 = INTEGER: 0
IF-MIB::ifIndex.4 = INTEGER: 0
IF-MIB::ifIndex.5 = INTEGER: 105001
IF-MIB::ifIndex.6 = INTEGER: 105002
IF-MIB::ifIndex.7 = INTEGER: 105003
IF-MIB::ifIndex.8 = INTEGER: 105004

Any ideas? Thank you very much for your help.

did you try using the 'reapply suggested graph names' action?

[floattent]

Thank you very much for your reply. I modified the sequence of the suggested values, and ran the "Reapply Suggested Names" command from the GUI, it didn't change anythingl. It looks to me that "query_ifXXXX" command is not working for the graph title. Any other place to take a look? Thank you very much for your help.

[BSOD2600]

Give \cacti\cli\poller_graphs_reapply_names.php a try. The problem is often the data is missing from the poller cache.

[floattent]

Thanks very much for the suggestions. However, it didn't help.

I also deleted the device and re-added it, then created the new graphs, it's still no good.

To simplified the queries, I created a new xml file as follows:

# more test.xml

</interface>

See the screen shots of the graph template as below:

[floattent]

The interesting thing is that I was able to see some interface name in the graph title. See the screen shot below.

[floattent]

I selected all the interfaces from this page, but only first 4 interfaces presented their name in the graph title. Why is that?

[floattent]

snmpwalk from the cacti server returns all the info for the ifDescr correctly.

I just realized that the interface can get the interface name parsed correctly all have an IP address attached to it. But for my most of the Ethernet interfaces, they don't have an IP address attached to them. I have removed the ifIP from the xml file, but it didn't help.

Any suggestion is highly appreciated. Thanks!

[BSOD2600]

you're taking the hard route on this by re-creating templates/scripts, etc. I'd suggest you remove them and go back to the stock template/script.

1) does a snmpwalk show ifDescr as you desire? it would appear so. good. means not a problem with the vendors implementation.
2) does a verbose output of the [SNMP - Interface Statistics] data query show the ifDescr. It would appear so. means cacti is able to properly query the device.
3) After using the 'create graphs for this host' screen, selecting the various interfaces, clicking on Create. Did Cacti use the correct ifDescr for all interfaces?

Hi BSOD2600,

Thank you very much for helping me on this one.

To answer your questions:
1) does a snmpwalk show ifDescr as you desire? it would appear so. good. means not a problem with the vendors implementation. -> Yes
2) does a verbose output of the [SNMP - Interface Statistics] data query show the ifDescr. It would appear so. means cacti is able to properly query the device. -> Yes
3) After using the 'create graphs for this host' screen, selecting the various interfaces, clicking on Create. Did Cacti use the correct ifDescr for all interfaces? -> No. It didn't show the ifDescr in the graph title at all for all the interfaces.

I have re-installed the cacti but still no luck. I have tried to create different graph types within the SNMP Interface Statistics template, it appeared to have the same issue. I'm totally lost. It shouldn't be that hard. Please help. Thanks very much!

[floattent]

Is that because there is some empty string in the "ifDescr" table? Can someone please confirm if this is the root cause of this issue? Thanks very much for your help.

IF-MIB::ifDescr.1 = STRING: Port_SDH-0-1-6-1
IF-MIB::ifDescr.2 = STRING: Port_SDH-0-1-7-1
IF-MIB::ifDescr.3 = STRING:
IF-MIB::ifDescr.4 = STRING:
IF-MIB::ifDescr.5 = STRING: Port_SDH-4-1-5-1
IF-MIB::ifDescr.6 = STRING: Port_SDH-1-1-5-5
IF-MIB::ifDescr.7 = STRING: Port_SDH-1-1-5-6
IF-MIB::ifDescr.8 = STRING: Port_SDH-1-1-5-7
IF-MIB::ifDescr.9 = STRING: Port_SDH-1-1-5-8
IF-MIB::ifDescr.10 = STRING: Port_Eth-100-1-4-1
IF-MIB::ifDescr.11 = STRING: Port_Eth-100-1-4-2
IF-MIB::ifDescr.12 = STRING: Port_Eth-100-1-4-3
IF-MIB::ifDescr.13 = STRING: Port_Eth-100-1-4-4

[BSOD2600]

Could be a bug I suppose... before diving into the code, what happens if you set a description for iface 3 and 4? Does it change Cacti's behavior?

[floattent]

I have very limited knowledge on the device, and I don't have time to learn how to set the ifDesc on those interfaces. I came across this old post, it looks like someone has already addressed a similar issue.

SNMP Query - ignore blank indexes
http://forums.cacti.net/viewtopic.php?f=21&t=43134

I do have some ifIndex with 0. See the screen show attached. Do you think it's the same issue?

I applied two patches that mentioned in that post. But when I tried to create the graphs again, I had same issue. How to verify the patches were actually applied? I had some issues when I applied the patch. Please advise. Thank you very much for your help.

[floattent]

I don't think this patch would work for me. Because I need to drop the entry that the ifIndex output is 0.
