I did not find the instructions on how to create graphics QOS.

Can you post screen shots of your data sources for this graph and the "Create Graphs for this Host" screen for the host?

[Setarcos]

Do you see any poller errors related to these queries file?

Per your PM: It appears your system isn't creating the data sources when generating the graphs for the host, and doesn't preserve the index values when attempting to do so for some reason. I see one discrepancy between your verbose query results and my own that might account for this. Can you post the version of snmp_persist.pl you have in /usr/local/sbin/snmp_persist.pl, and your version of linux_qos.xml?

[saaremaa]

I installed linux_qos.xml and snmp_persist.pl of Linux-QoS.zip (http://forums.cacti.net/download.php?id=14980)

Today I replaced snmp_persist.pl latest available files snmp_persist.pl(http://forums.cacti.net/download.php?id=15250) file and restarted snmpd.

My current linux_qos.xml and snmp_persist.pl

Today I replaced snmp_persist.pl latest available files snmp_persist.pl(http://forums.cacti.net/download.php?id=15250) file and restarted snmpd.

Please be sure to set $debug = 0, or snmpd won't know what to do with the debugging output.

I'm still digging, but haven't found anything noticeably out of place that would cause this yet.

You have found a fix?

Sorry, I have not. From what I can tell, the data sources should be getting created properly when creating new graphs from the host screen, but they are loosing the indexes.

Does your Cacti install have anything other than the vanilla Cacti 0.8.7d base (e.g. Boost, PIA)? I saw your server do a few weird things while using it, and wondered if this might be related to one of these.

[saaremaa]

Cacti 0.8.7d only installed + my scripts for Cacti.
My written scripts for Cacti does not use SNMP.

Was this ever solved, I'm having a similar issue.

[mates007]

I installed snmp-persist.pl and snmp-persist-test.pl on my debian etch router/firewall.

When running the script, it freezes after printing found NICs.

Code: Select all

sudo -u snmp /usr/local/bin/snmp_persist-test.pl
Found NIC=lo
Found NIC=eth0
Found NIC=eth1
Found NIC=eth2
Found NIC=wifi0
Found NIC=wlan0
Found NIC=tun0
Found NIC=tun1
Found NIC=tap0
Found NIC=sit0
Found NIC=sixxs
Found NIC=tap1
Found NIC=tun2

I have to ctrl+c after several minutes.

I didn't put it intosnmpd.conf yet, as the script doesn't work. What could be a problem?

This would be a long shot, but did anyone ever solve this?

OK, I found it. Index value must be unique, so with this same classid on different interfaces going to problem.
I made basic patch, adding interface name to index value:

Thanks for the response, sorry it has taken me this long to get back. It still does not create graphs, but I run the command from the data source debug output it creates the graph but does not put any data into it.

[sles]

OK, I found it.

Hello!

Unfortunately, this patch even can't be applied:


[root@p100-vpn-x cacti]# patch -p0 <snmp-persist.patch
patching file snmp_persist.pl
Hunk #1 FAILED at 133.
Hunk #2 FAILED at 174.

But I found right places and still have the same problem as before patch:

[root@p100-vpn-x cacti]# ./snmp_persist-test.pl
Found NIC=lo
Found NIC=eth0
Found NIC=eth1
Found NIC=sit0
Found NIC=gre0
Found NIC=gre1
Found NIC=eth0
Found NIC=eth0


This is CentOS 5.6 and I have vlan interfaces- eth 0.6 and eth0.29, looks like these are last two eth0, but they are not reconised correctly.
May be somebody already fixed this?

Thank you!

[sles]

OK, really I have htb only on gre1, so I created following quick hack, so only htb interfaces are listed:

sub nics() {
my @niclist = `$ipcmd link show`;
my (@nic, $line, $lilnic);
foreach $line (@niclist) {
# ($lilnic) = $line =~ /^[0-9]+:\s+([a-z0-9]+)/ or next;
if ( index($line, "qdisc htb") > -1 ) {
($lilnic) = $line =~ /^[0-9]+:\s+([a-z0-9]+)/ or next;
print "Found NIC=$lilnic\n" if $debug;
# print "Found NIC=$line\n" if $debug;
push(@nic, $lilnic);
}
}
return(@nic);
}


It works

[carlosbrolo]

Can I have help?

Currently I managed the script to work, but is only reporting "HTB 1" traffic not the classes inside it.
I mean, on Cacti I only see eth0 as interface name, and htb1 as qdisc name..... No tc classes to graph.

System: Ubuntu 9.10

My TC structure was made using:

Code: Select all
