        <description><![CDATA[<p>Hello,</p><p>We have been successfully running an lpar2rrd server in Openshift for a few years; however we have only been collecting HMC data.  We would like to add aix osagent data too.  We have installed the osagent and created a route in Openshift to direct the connection to port 8162 of the openshift POD.  When we try to run the agent we get a Connection refused error.  After troubleshooting with our openshift team it turns out that the way we have our Openshift setup it only allows incoming requests to ports 443 or 80 through to the load balancer and then it gets redirected to the appropriate port/POD.  For example a connection attempt from an aix client to openshift_lpar2rrd_server@somewhere.com:8162 will not work.  It would need to be openshift_lpar2rrd_server@somewhere.com (Which has a route pointed to port 8162).  </p><p>Has anyone else ran into this?</p><p>Thanks</p>]]>

        <description><![CDATA[<p>Hi all</p><p>First thanks to all for this great software.</p><p>I have an issue installing the dscli into the official Linux Alpine xorux/stor2rrd docker image. First I create a dockerfile as a following:</p><div>

</div>
<p></p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p>This dockerfile install libc and openjdk8 as requirements for dscli install bin file to work.</p><p>But, when I try to run the dscli installer, this fail, maybe due java issues.``</p><div>
    <div>
        <a href="https://forum.xorux.com/uploads/17V7PDCMJB5N/image.png" rel="nofollow noreferrer noopener ugc" target="_blank">

    </div>
</div>
<p>The second option that we have to make dscli installer works is change the openjdk java for ibm java.</p><p>But the IBM java installer fail when I try to install into the alpine stor2rrd docker image container.</p><div>
    <div>
        <a href="https://forum.xorux.com/uploads/P7FRZPJW0Q50/image.png" rel="nofollow noreferrer noopener ugc" target="_blank">

</div>
<p>Any clue or suggestion to have the IBM dscli running into the official stor2rrd docker image?</p><p>I will apreciate any help.</p><p>Regards</p><p>Victor S.</p>]]>

The data size increased really too fast.<br />   I'm not sure how can we utilize it effectively to monitor clouds in long duration, such as for weeks or months?<br />   Could you share some ideas? <br /><br /><br />Kind Regards,<br />Justin]]>
