Question by Michel Croibier · May 14, 2010 at 04:16 PM · wowza streaming engine in the cloud

CACTI not showing Wowza graphs

Hi,

This is for sure a beginner question...

I setup Cacti and now I can see the network and system graphs in the tree.

However nothing shows up in the Wowza leaf...

I am using ami-fd674d89 without any modifications.

Any help appreciated.

Thanks

Regards

Michel

Is there any activity through Wowza as you look? Try streaming a video from that instance with SimpleVideoStreaming or some other example.

Yes, I have a live stream running, I can connect to it with the sample player provided.

I can also see the connections in http://[SERVER_IP]:8086/connectioncounts

but no graphs in the Wowza server section of Cacti...

I think it takes some time, possibly 15 minutes or so, to start to show.

Did you follow the setup setups in the Wowza EC2 guide. You have to uncheck a box and save. See the "Monitoring the Wowza Media Server on EC2 using Cacti" chapter.

5) On the "Management: Devices" page click the "Localhost" device in the "Description" column.

6) Uncheck the "Disable Host" setting in the "General Host Options" section of the page. Then click the "Save" button at the bottom of the page.

Then wait 60 seconds to start seeing graphs.

Thanks Richard,

Yes the check box is unchecked.

Otherwise I could not even get network and system graphs...

Only the Wowza graphs are not showing up...

Here's the "devices" page telling the wowza graphs are "Being graphed"

However, nothing shows in "Graph" page :

And the log contains error somehow connected to the Wowza graphs data sources :

It does seem like something is wrong. Can you try launching another instance?

If you just started a new instance and anything is not working right the best thing to do is to terminate it and start another one.

I have just terminated it, and started a new one. Same problem again.

I have removed the "Disable Host" checkmark.

I am livestreaming to the "live" application.

The network and System Graphs are fine, but the "Wowza media server" graphs does not show anything.

I tried it recently with us-east-1 small instance and had no problem. Will have to get back to you about this.

I tried it with that same AMI and it worked for me. Are you sure you are following the steps to enable in the EC2 guide? I guess it could be bad luck with 2 instances in a row, but I cannot replicate the problem.

Hi Esso74,

I fired up a new instance this morning and Cacti detected and graphed RTSP live streams fine. Please send an email with the details of what you're seeing to support@wowza.com and we'll get things sorted out.

Take a look at the "Adding Additional Wowza Server Graphs" chapter of the Wowza EC2 User Guide.

I can't find "Cacti" in recent WowzaMediaServerForEC2_UsersGuide.pdf

BTW, we are using Wowza 2.2.4, where can I download UserGuide for this version?

Thanks,

Anatoly

Answer by Craig Burriss · Jun 16, 2010 at 09:19 AM

I tested the EU-Instances and Cacti is graphing correctly for me.

There are two common issues when using Cacti to watch out for. One is that the Cacti system checks for connections once every 60 seconds or so. If you watch 45 seconds of a stream then stop the system may not log you as a viewer. The second is the graphing time range is not good about reseting to the current time. If you load the graph page and select 'last half hour' as your time frame it loads the current time and last half hour. But if you go to lunch and come back, even if you refresh the page the system will still have the old 'half-hour' times loaded. In these cases you must manually set the time frame you wish to view.

All seems well with Cacti monitoring on my EC2 instance and we have a couple of streams running 24/7 but no streams show up in the graph Localhost - Wowza Server - Stream ([name]) Connections. All client and server connections show up fine.

Is this graph template expected to automatically graph all current streams and substitute the field name automatically or is there a manual substitution?

If manual please explain procedure. I would like to monitor activity stream by stream.

Thx
