vCenter 6 Performance charts service returned an invalid response

Performance overview charts are important to any vSphere admin’s life. I often use these as a starting point to troubleshoot contention issues, utilizing advanced charts after consulting the overview. It wasn’t long after upgrading our Windows vCenter server from 5.5 to 6.0 that we noticed we could no longer view performance overviews for any object. Hosts, and VM’s would return “Performance Charts service returned an invalid response” error message.

Invalid Response

This would only happen if we logged in with our domain credentials. As a temporary work around we could log in under our @vsphere.local accounts to view the overview stats. Advanced stats worked regardless of which account we’d use.

After working with VMware support for some time on this issue, the following fix was identified and was successful in returning this important functionality.

Open C:\ProgramData\VMware\vCenterServer\data\perfcharts\tc-instance\conf\server.xml

Append the following to both the ipv4 and ipv6 configuration sections…

maxHttpHeaderSize="65536"

For example my configuration looks like this…

<!-- IPv4 configuration -->
        <Connector address="127.0.0.1"
                   acceptCount="300"
                   maxThreads="300"
                   connectionTimeout="20000"
                   executor="tomcatThreadPool"
                   maxKeepAliveRequests="15"
                   port="${bio.http.port}"
		   maxHttpHeaderSize="65536"
                   protocol="org.apache.coyote.http11.Http11Protocol"/>
        <!-- IPv6 configuration -->
        <Connector address="::1"
                   acceptCount="300"
                   maxThreads="300"
                   connectionTimeout="20000"
                   executor="tomcatThreadPool"
                   maxKeepAliveRequests="15"
                   port="${bio.http.port}"
		   maxHttpHeaderSize="65536"
                   protocol="org.apache.coyote.http11.Http11Protocol"/>

Then restart the VMware Performance Charts service via services.msc or by executing the following from an administrative command prompt…

C:\Program Files\VMware\vCenter Server\bin\service-control --stop vmware-perfcharts
C:\Program Files\VMware\vCenter Server\bin\service-control --start vmware-perfcharts

  1. Well this is another reason that the web client is a failure. The charts work fine in the regular vSphere client.

    Anyway, thank you, and I hope VMware is paying you to fix their problems for them, since they are too busy to do it themselves.

  2. Thanks for the tip, Matt! This also works for VCSA: /usr/lib/vmware-perfcharts/tc-instance/conf/server.xml. As a side note, this issue has something to do with AD group membership. Maybe the number of nested groups? If I created a new user and assigned admin permissions to vCenter, that user was able to see the perfchart overview. I wasn’t able to open the perfchart overview with my existing admin account until I implemented your fix! Thanks again.

  3. This is the only article I could find that fixed this issue. Thanks.
