[Ganglia-general] Cluster setup
Hi
I am quite new to ganglia, so I am having trouble setting it up like I want it.
We are running a hpc-cluster and I want ganglia to monirot three sub-clusters.
Admin
Workstation
Computational
I have found some hints on how to do this, but nothing is working. I am able to
monitor a few machines individually, but not to collect them into clusters. No
I am doing
Gmetad.conf
Data_source machine1 machine1
Data_source machine2 machine2
Gmond.conf
Cluster {
Name = machine1
..
}
Udp_send_channel {
Host = machine1
Port = 8649
}
If I change host in send_channel to something else, and I do telnet to look at
the xml-file then no metrics are sent.
Anybody have any tips?
Regards Peter

Have you configured any udp_recv_channel sections?

[Ganglia-general] vlan traffic counting
I've noticed on our VLAN interfaces that gmond's default network metric
seem to be miscalculating network traffic.
anyone else seeing this? we don't use many VLANs.
seems the Linux OS counters for the VLAN interface also add onto on
the parent interface, and gmond reads both so traffic reported by gmond
is ~2x greater than it really is.
eg. eth4 (no IP set) with a eth4.99 VLAN, /proc/net/dev shows
Inter-| Receive| Transmit
face |bytespackets errs drop fifo frame compressed multicast|bytes
packets errs drop fifo colls carrier compressed
...
eth4:1453106293850 1688242724000 0 0 11874
3090232715347 2518006182000 0 0 0
eth4.99:1429470895714 1688242724000 0 0 11874
2988353281655 912706240000 0 0 0
maybe we have setup our interfaces oddly or something.
I don't know why Tx Pkts is different between the 2 interfaces ...
maybe an upstream MTU.
aliased interfaces don't have the same problem as Linux doesn't list
them in /proc/net/dev.
our setup is ganglia 3.2.0, x86_64, centos5.6 userland, 2.6.32 vanilla
kernels, ixgbe 10gige.
the below patch fixes/hacks-around the problem by simply skipping all
VLAN interfaces - anything with a '.' in the name.
doesn't seem right somehow, but seems to work for me.
cheers,
robin

Re: [Ganglia-general] Problem displaying Virtual Machine data with hsflowd and ganglia 3.2.0 in an Openstack Compute node.
Hi, I downloaded and installe hsflowd trunk revision 226 but using hsflowd I keep seeing virStorageLookupByPath errors, and VM disk statistics aren't displayed. Do I need to tell hsflowd explicitly to use target=vda call? If yes, how? Thanks in advance, Emanuele 2011/8/25 Emanuele Verga verga.emanu...@gmail.com Hi Neil, Yes that's possible, the problem is Nova places each image in a separate folder (/var/lib/nova/instance/INSTANCENAME/), so we would have to create a new pool with the corresponding path each time a new instance is created, and if we start to add more servers it quicly becomes impractical. I've not yet been able to try the hsflowd version you suggested, I'll test it tomorrow and let you know. Thanks for the help!

Re: [Ganglia-general] Problem displaying Virtual Machine data with hsflowd and ganglia 3.2.0 in an Openstack Compute node.
Sorry, the failure of virStorageLookupByPath() was preventing virDomainBlockStats() from being attempted. I checked in a fix for this, and also code to try the newer virDomainGetBlockInfo() call as a fallback should virStorageLookupByPath() fail. This call only came in with libvirt version 0.8.1. Are you running something newer than that? (see /usr/include/libvirt/libvirt.h) If this works, we should make a new release of hsflowd, so please let me know how it goes.

[Ganglia-general] Ganglia Web 2.1.6 - Host Display Errors
I updated to the 2.1.6 web frontend, but I am still experiencing the same reported issues (problems showing Host Overview for more than a second) from the 2.1.5 release. I noticed in a previous thread that a new host_view.tpl was created for this issue, but in the 2.1.6 release the date on the file host_view.tpl is 2011-08-19. I was wondering what steps would be needed to correct this issue?

Re: [Ganglia-general] Ganglia XML error: required
Hi Alex, The telnet and xmllint gives the success result. I am not sure it could be because of xml_parse logic done on ganglia.php (web interface files) It reads entire xml in chunks of 16384 bytes and parses it till the end of file. In one of the post I read about the same issue and suggested to read entire xml into a variable and parse all at once.

[Ganglia-general] Set the default value for metric (RRD datasource value)
Hi, RRD expects the value for a metric(data source) on fixed interval. If the metric value cannot be generated on time, by default RRD stores it as 'Nan'. Is there any way to handle this case where in I want to initialise the value to 0 in case of metric doesn't get value in the required time slot.
