WLST capture the output of state('ms1') to a variable - weblogic

Question

I need to capture the output of the below to a variable.
I know we can get to serverRuntime or domainRuntime() trees and get the state. But need to get the below working.
wls:/owb/serverConfig> state('Server1')
Current state of 'Server1' : RUNNING
I tried two ways:
wls:/owb/serverConfig> print state('Server1')
Current state of 'Server1' : RUNNING
None
wls:/owb/serverConfig> x=state('Server1')
Current state of 'Server1' : RUNNING
wls:/owb/serverConfig> print x
None

Answer 1

You have to use the getState() method of server runtime mbean.
You can obtain the server runtime mbean by navigating into wlst runtime tree or by using a lookup method.
Sample:
domainRuntime()
slrBean = cmo.lookupServerLifeCycleRuntime('Server1')
status = slrBean.getState()
print 'Status of Managed Server is '+status
See also Getting Runtime Information in WLST official documentation.

This same question was raised by Dianyuan Wang with me 2011.
Here is the steps to resolve your issue.
1. Capture the output of state command using redirect, stopRedirect command
2. Use the Python regular expression in search function to extract the desired server output.
Code snippet is here
fileName='/tmp/myserver_state.txt'
redirect(fileName)
state(server_nm,'Server')
stopRedirect()
f = open(fileName)
try:
for line in f.readlines():
if re.search('Current state',line):
status[server_nm]=line
except:
continue
Now you can apply desired logic after this block.

Here is what I am using and is working like charm
cd("/ServerRuntimes/ms1")
state=cmo.getState()
print state
