Hello, I am using storm ui rest api to get some metrics. However when
doing so, after some time the ui.log shows too man open files error.
Using lsof -p <PID of UI> and see a lot of information like "can't
identify protocol". The python code used to fetch the data is list
below. Could anyone help me please? Thank you!!
*import urllib2**
**import json**
**
**top_summary_url='http://nz:8080/api/v1/topology/summary'**
**
**def getCapMetric(topname,components):**
** urlstr = 'http://nz:8080/api/v1/topology/' +
getTopologyId(topname) + '/component/' + components**
** f=urllib2.urlopen(urlstr)**
** response =json.load(f)**
** f.close()**
** avg_cap=0**
** for dic in response['executorStats']:**
** avg_cap+=float(dic['capacity'])**
** avg_cap/=len(response['executorStats'])**
** return avg_cap**
**
**def getTopologyId(topname):**
** response=json.load(urllib2.urlopen(top_summary_url))**
** for dic in response["topologies"]:**
** if dic['name']==topname:**
** return dic['id']**
