You can also check that you are able to see flow in the past like this: g.At('-1s').V().Has('Name', Regex('_openshift-infra_')).Out().Has('Type', 'veth').Flows() It will return you flows that were existing 1 sec ago, this test will validate that the datastore is working correctly. In order to get flows and metrics you have to have a capture started thanks to the WebUI or the command line. <div class="HOEnZb"><div class="h5"> Thanks, Sylvain ----- Mail original ----- > Thanks Nicolas, can do the query now and get results with both queries: > > docker run --net=host -ti skydive/skydive client --analyzer > <a href="http://172.30.27.26:8082" rel="noreferrer" target="_blank">172.30.27.26:8082</a> topology query --gremlin "g.V().Has('Name', > Regex('_openshift-infra_')).Out().Has('Type', 'veth')" > > docker run --net=host -ti skydive/skydive client --analyzer > <a href="http://172.30.27.26:8082" rel="noreferrer" target="_blank">172.30.27.26:8082</a> topology query --gremlin "g.V()" > > But I'm getting empty results when I try to query for flows: > > docker run --net=host -ti skydive/skydive client --analyzer > <a href="http://172.30.27.26:8082" rel="noreferrer" target="_blank">172.30.27.26:8082</a> topology query --gremlin "g.V().Has('Name', > Regex('_openshift-infra_')).Out().Has('Type', 'veth').Flows()" > > This query only returns values when doing a capture at the same time using > Skydive web Interface, but still returning empty values to Grafana. > > So what are the steps to get the flows to Grafana? > > Thanks, > Mak > > > > , but I'm still getting a grafana empty result while using the query: > > > > > > On Thu, Mar 2, 2017 at 3:56 AM, Nicolas Planel <<a href="mailto:nplanel@redhat.com">nplanel@redhat.com</a>> wrote: > > > Hi Marcos, > > > > > > Yes you can add --analyzer <a href="http://172.30.27.26:8082" rel="noreferrer" target="_blank">172.30.27.26:8082</a> on the command line like : > > docker run --net=host -ti skydive/skydive client --analyzer > > <a href="http://172.30.27.26:8082" rel="noreferrer" target="_blank">172.30.27.26:8082</a> topology query --gremlin "g.V()" > > > > Other solution could be use -c skydive.yml or the environment variable > > SKYDIVE_ANALYZER > > > > > > Regards, > > > > Nicolas > > > > > > On Thu, Mar 2, 2017 at 1:37 AM, Marcos Entenza Garcia <<a href="mailto:mak@redhat.com">mak@redhat.com</a>> > > wrote: > > > >> Is it posible to specify the IP?
