The problem is this: (Ambari Version and the Ambari Metrics Component version should be same)

# rpm -qa | grep ambari
 ambari-metrics-collector-2.1.0-1470.x86_64
 ambari-metrics-monitor-2.1.0-1470.x86_64
 ambari-server-2.2.2.0-460.x86_64 
 ambari-metrics-hadoop-sink-2.1.0-1470.x86_64 
 ambari-agent-2.2.2.0-460.x86_64

.

Looks like you have not performed the Amabri Post upgrade steps hence your AMS binaries are still Old (2.1.0). where as ambari binaries are 2.2.2

1. Stop the AMS collector Service from ambari UI and then perform the AMS post upgrade steps: https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_upgrading_Ambari/content/_upgrade_ambari...

Please verify that you have the correct ambari.repo: (repo should be from 2.2.2 version NOT from 2.1.0)

# cat /etc/yum.repos.d/ambari.repo | grep 2.2.2

2. So please do this on all the hosts where you see AMS binary version as 2.1.0

# yum clean all
# yum upgrade ambari-metrics-monitor ambari-metrics-hadoop-sink

.

3. And on the host where Ambari Metrics Collector is installed Please do this:

# yum upgrade ambari-metrics-collector

.

The following error indicates that somehow the yum installation is not happening:

Fail(err_msg) resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install ambari-metrics-monitor' returned 1. 
Error: Nothing to do stdout: 

.

So can you please try to do the manual installation of monitor Binaries on that host as following and then continue from Ambari Server UI.

# yum clean all
# yum remove ambari-metrics-monitor
# yum install ambari-metrics-monitor

.

Sometimes incomplete transaction at yum level causes such issue so better to remove the incomplete binary installation first and then try installing it again.

Also please check if the "/etc/yum.repos.d/ambari.repo" file on that host is pointing to the correct repo URL and that URL is accessible from the host ?

# cat /etc/yum.repos.d/ambari.repo
# cat /etc/yum.repos.d/ambari.repo  | grep baseurl

.

Re: ambari monitor failed to start

Hi Jay , Thanks for responding , I tried the commands and it showed

# yum remove ambari-metrics-monitor

Loaded plugins: fastestmirror, refresh-packagekit, security Setting up Remove Process No Match for argument: ambari-metrics-monitor Loading mirror speeds from cached hostfile * base: mirror.den1.denvercolo.net * extras: mirror.raystedman.net * updates: mirror.compevo.com No Packages marked for removal

it seems the packages are unavailable

@Krupal Jagtap

AMS monitor should come from Ambari repo (not from HDP repo) so please check if you have the amabri.repo file present on that host or not?

# cat /etc/yum.repos.d/ambari.repo

.

If not then please copy and paste that repo file from ambari-server host to this host.

Also please make sure that the host where the AMS monitor installation is failing does not have any N/W issue. THis is to ensure that the yum installation for AMS monitor happens without any issue.

Re: ambari monitor failed to start

hi Jay , SO the repo file was missing so I copied that file on the host and the metrics monitor started, But it still doesnt show any data on the metrics GUI . The square boxes prompt "no data available"

Re: ambari monitor failed to start

@Krupal Jagtap

Good to know that now at lease the AMS monitor is coming up.

Regarding the "No data available" issue please share the "/var/log/ambari-metrics-monitor/ambari-metrics-monitor.out"

Also please check if the "/etc/ambari-metrics-monitor/conf/ambari-metrics-monitor.ini" file is pointing to the Correct Hostname of AMS Collector?

Re: ambari monitor failed to start

HI so the ambari-metrics-monitor.ini file seem to be pointing at the right host

here is the log for ambari-metrics-monitor.out

Re: ambari monitor failed to start

Hi jay , The delete option for ams monitor is disabled in the ambari UI . How should I go about deleting it and reinstalling it again?

Re: ambari monitor failed to start

Super Mentor

@Krupal Jagtap

The following error might occur if you have installed a slightly different version of Ambari Metrics Monitor compared to the ambari version and hence there are some library mismatch.

[WARNING] emitter.py:74 - Error sending metrics to server. 'NoneType' object has no attribute 'strip' 2

.

Please check the output of the following command and verify if all the ambari component versions are same?

# rpm -qa | grep ambari

.

Better to freshly try installing the ams monitor. From ambari UI just remove the metrics monitor process and then try installing it again.

Re: ambari monitor failed to start

I tried the commannd you mentioned and it returned following value

ambari-metrics-collector-2.1.0-1470.x86_64

ambari-metrics-monitor-2.1.0-1470.x86_64

ambari-server-2.2.2.0-460.x86_64

ambari-metrics-hadoop-sink-2.1.0-1470.x86_64

ambari-agent-2.2.2.0-460.x86_64

And if i had to remove the process and try installing again, How would I go about doing it?
