=head2 Package Description
|
|
This is a xCAT monitoring plugin. The only thing that this plug-in does is
|
|
the node monitoring. To activate it simply do the following command:
|
|
chtab pname=xCAT monitoring.nodestatmon=Y

=head3 start
|
|
This function gets called by the monitorctrl module when monstart command
|
|
gets called and when xcatd starts.

callback -- the callback pointer for error and status displaying. It can be null.
|
|
Returns:
|

" Description:
|
|
xcatmon provides node status monitoring using fping on AIX and nmap on Linux.
|
|
It also provides application status monitoring. The status and the appstatus
|
|
columns of the nodelist table will be updated periodically with the latest
|
|
status values for the nodes. Use command 'monadd xcatmon -n' and then
|
|
'monstart xcatmon' to start monitoring.
|
|
Settings:
|
|
ping-interval: the number of minutes between each fping operation.
|
|
The default value is 3.
|
|
apps: a list of comma separated application names whose status will be queried.
|
|
For how to get the status of each app, look for app name in the key filed
|
|
in a different row.
|
|
port: the application daemon port number, if not specified, use internal list,
|
|
then /etc/services.
|
|
group: the name of a node group that needs to get the application status from.
|
|
If not specified, assume all the nodes in the nodelist table.
|
|
To specify more than one groups, use group=a,group=b format.
|
|
cmd: the command that will be run locally on mn or sn.
|
|
lcmd: the command that will be run locally on the mn only.
|
|
dcmd: the command that will be run distributed on the nodes using xdsh.
|
|
|
|
For commands specified by 'cmd' and 'lcmd', the input of is a list of comma
|
|
separated node names, the output must be in the following format:
|
|
node1:string1
|
|
node2:string2
|
|
...
|
|
For the command specified by 'dcmd', no input is needed, the output can be a
|
|
string.";
