Adding Resources
ELIM restart
For example, elim.license.exe
If LIM expects some resources to be collected by an ELIM according to
configuration, it invokes the ELIM automatically on startup. The ELIM runs with
the same user ID and file access permission as the LIM.
The LIM restarts the ELIM if it exits; to prevent problems in case of a fatal error
in the ELIM, it is restarted at most once every 90 seconds. When the LIM
terminates, it sends a SIGTERM signal to the ELIM. The ELIM must exit upon
receiving this signal.
Example 1 Write an ELIM.
The following sample ELIM (LSF_SERVERDIR/elim.mysrc) sets the value
of myrsc resource to 2. In a real ELIM, you would have a command to
retrieve whatever value you want to retrieve and set the value.
#!/bin/sh
while :
do
# set the value for resource "myrsc"
val=2
# create an output string in the format:
# number_indices index1_name index1_value...
reportStr="1 myrsc $val"
echo "$reportStr"
# wait for 30 seconds before reporting again
sleep 30
done
2 Test this ELIM by running it from the command line.
% ./elim.myrsc
It should give you the output:
1 myrsc 2
3 Copy the ELIM to LSF_SERVERDIR and make sure it has the name
elim.myrsrc.
4 Define the myrsc resource in lsf.shared.
In this case, we are defining the resource as Numeric because we want it
to accept numbers. The value does not increase with load.
Begin Resource
RESOURCENAME TYPE INTERVAL INCREASING DESCRIPTION
myrsc Numeric 30 N (custom resource to trigger elim to
start up)
End Resource
5 Map the myrsc resource to hosts in lsf.cluster.cluster_name. In this
case, we want this resource to reside only on hostA.
