Hello,
in case somebody has a NoMachine NX cluster, and is suffering from its dumb round-robin dispatcher, here is a solution:
nxpub (NX Pluggable User Balancer).
It should run on all LUnix OS. Scripts for install/uninstall are supplied.
While tested with NX 3 (NX 3.5 is the latest), it might run on the older NX 2 and can be ported to NX 4 or Open NX.

Hi All,
How do I failover on the ip load balancer (back and forth)? It involves first to load a new config on the passive ip. If success, load the new config on the ip active (which is now passive).
Any idea, please.
Thanks in advance. (0 Replies)
Hi,
What's the best load balancer for Linux (CentOS, SuSE) according to your personal experience?
Linux Virtual Server (LVS) is a famous one, but their download site has not been updated since 2007. Their web and mailing list are so quiet. Is the Ultra Monkey project including LVS... (1 Reply)
we use piranha load balancer with two nodes
even the primary node is running fine and up failover happend to secondary node
this happend quite few times ehy node2 cannot talk to node1
what logs are to be checked and investigate why failover occured
pulse: partner dead: activating... (0 Replies)
Hello Guys,
Hope you all doing well . :)
I was checking load balance command (uptime)on VM server and got below output.
# uptime
07:08:40 up 52 min, 2 users,a load average: 0.45, 0.11, 0.03
A :How we can calculate load average?
Thank you in advance !!
Cheers:)

cluster
CLUSTER(1) General Commands Manual CLUSTER(1)NAME
cluster - find clusters in a graph and augment the graph with this information.
SYNOPSIS
cluster [-v?] [ -Ck ] [ -ck ] [ -o outfile ] [ files ]
DESCRIPTION
cluster takes as input a graph in DOT format, finds node clusters and augments the graph with this information. The clusters are specified
by the "cluster" attribute attached to nodes; cluster values are non-negative integers. cluster attempts to maximize the modularity of the
clustering. If the edge attribute "weight" is defined, this will be used in computing the clustering.
OPTIONS
The following options are supported:
-Ck specifies a targeted number of clusters that should be generated. The specified number k is only a suggestion and may not be real-
isable. If k == 0, the default, the number of clusters that approximately optimizes the modularity is returned.
-ck specifies clustering method. If k == 0, the default, the modularity will be used. If k == 1 modularity quality will be used.
-ooutfile
Specifies that output should go into the file outfile. By default, stdout is used.
-v Verbose mode.
EXAMPLES
Applying cluster to the following graph,
graph {
1--2 [weight=10.]
2--3 [weight=1]
3--4 [weight=10.]
4--5 [weight=10]
5--6 [weight=10]
3--6 [weight=0.1]
4--6 [weight=10.]
}
gives
graph {
node [cluster="-1"];
1 [cluster=1];
2 [cluster=1];
3 [cluster=2];
4 [cluster=2];
5 [cluster=2];
6 [cluster=2];
1 -- 2 [weight="10."];
2 -- 3 [weight=1];
3 -- 4 [weight="10."];
4 -- 5 [weight=10];
5 -- 6 [weight=10];
3 -- 6 [weight="0.1"];
4 -- 6 [weight="10."];
}
