Hello Gautam, thanks for the answer. And sorry about the delay. I changed the property and restarted impala service, but the error occured again: [22/Jul/2015 12:51:27 +0000] 2502 ImpalaDaemonQueryMonitoring throttling_logger ERROR (3318 skipped) Error fetching metrics at 'http://cloudera01-vm.spiegel.de:25000/jsonmetrics?json' Traceback (most recent call last): File "/usr/lib64/cmf/agent/src/cmf/monitor/abstract_monitor.py", line 394, in collect_metrics_from_url result = self.parse_metrics(simplejson.load(openedUrl)) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/simplejson-2.1.2-py2.6-linux-x86_64.egg/simplejson/__init__.py", line 328, in load use_decimal=use_decimal, **kw) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/simplejson-2.1.2-py2.6-linux-x86_64.egg/simplejson/__init__.py", line 384, in loads return _default_decoder.decode(s) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/simplejson-2.1.2-py2.6-linux-x86_64.egg/simplejson/decoder.py", line 402, in decode obj, end = self.raw_decode(s, idx=_w(s, 0).end()) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/simplejson-2.1.2-py2.6-linux-x86_64.egg/simplejson/decoder.py", line 418, in raw_decode obj, end = self.scan_once(s, idx) JSONDecodeError: Expecting property name: line 75 column 19 (char 2309) But - then i changed the locale from de_DE.UTF-8 to en_US.UTF-8 systemwide (in /etc/sysconfig/i18n) and the impala monitoring works fine! Thanks for the help Markus

forgot to say, that this thread describes nearly the same problem, but the solution did not work for us: http://community.cloudera.com/t5/Cloudera-Manager-Installation/CDH-5-4-Impala-webinterface-monitoring/m-p/26907/highlight/true#M4322

Hello @All, we are running CDH 5.4.4 and Cloudera Manager 5.4.3 on Centos 6.4 Systems Everything runs fine except the impala Monitoring. The service itself is also running fine. It seems that only the monitoring of the impala daemons on all hosts and the catalogserver is not working: impala: Health Issues catalogserver (cloudera06-vm) Web Server Status impalad (cloudera01-vm) Impala Daemon Ready Check, Web Server Status impalad (cloudera02-vm) Impala Daemon Ready Check, Web Server Status impalad (cloudera03-vm) Impala Daemon Ready Check, Web Server Status impalad (cloudera04-vm) Impala Daemon Ready Check, Web Server Status impalad (cloudera05-vm) Impala Daemon Ready Check, Web Server Status The error-Messages are as follows: "The Cloudera Manager Agent got an unexpected response from this role's web server.
