To whom it may concern,

I have tried to install DEM monitor in one of our VMs (Ubuntu 12.04.02), apparently the installation is ok but the DEM module does not write on Orion.

@Panos, I have some questions for you.

· Please, find attached the monitoring.cfg file, is this correct? (The private ip of our Orion VM is 10.0.0.90).

· If I try to check open stack metadata API with the “curl http://169.254.169.254/openstack/latest/meta_data.json” I get a result that is different from the output mentioned in the guide ( {"random_seed":"qmsKI/YXTisafsEEueV8J4HZdKPu0yXH…… ):

Is this correct?

root@finesce-wp4-dev-server:~# curl http://169.254.169.254/openstack/latest/meta_data.json

1.0

When I have started the vmonitorS service I got the correct message as written in the “PDEM_ver1.0-1.pdf” guide:

root@finesce-wp4-dev-server:~# $sudo service vmonitorS start

Starting NG Service Update ...

Update service started!

The log file is created but nothing is written on Orion. (find attached the monitor.log file)

Where am I wrong?

Thanks in advance

Leandro

Hi Leandro,

Passive DEM component is the latest version of DEM.

You can find it here: https://xifisvn.res.eng.it/wp3/software/DEM_Adapter/PDEMv1.0/

Download it, either for Ubuntu or CentOS (depending on the OS of the VMs you want to monitor).

Installation procedure is included in the abovementioned folder.

After installation, please modify the configuration file as mentioned in the instructions.

The whole procedure is straightforward, however, if you need assistance please do not hesitate to contact me.

Best regards,

Panos.

Θέμα: Monitoring VMs

Hi, Leandro.

Related to our discussion regarding issue HELP-1525, let me put my colleagues Panos and Fernando in the loop. First of all, let me quote an excerpt of our conversation to give them some context:

“[…] I am going to give you details about the scenario where we are working on FINESCE (which is 2nd phase project, like FITMAN). We have to integrate FIWARE GEs in the architecture of an energy marketplace (which is the output of FINESCE WP4). We have set up a couple of VMs into FI-Lab; there, both all the software developed within FINESCE Wp4 and our “private” instance of GEs (such as ORION or PROTON) are running. We need to increase the number of GEs we have to integrate as our target KPI is very ambitious.

We thought we could have used Monitoring GE in order to monitor the state of our private instance of GEs. […]”

In order to monitor instances (VMs), you’ll need the XIFI’s DEM module <http://wiki.fi-xifi.eu/Public:DEM> installed on them, and an instance of Orion Context Broker that will receive monitoring data. @Panos could help you with DEM, while we (Fernando and myself) could give support regarding Context Broker. Please do NOT pay attention to DEM’s architecture design <http://wiki.fi-xifi.eu/Public:DEM#Architecture_design> as it is outdated: neither Nagios nor Event Broker nor NGSI Adapter are now required.

“[…] would you provide a panel to be used by FI-Lab users? […]”

Yes. Currently, there are two panels available: the infographic panel <http://infographic.lab.fi-ware.org/> and the status panel <http://infographic.lab.fi-ware.org/status> . Monitoring data (both current and historical) are processed and stored, and will eventually be accessible for users.

“[…] More, if we would like to monitor the VM where our instance of ORION is running, for instance, would we need to have an agent installed on it? Would you be in charge for the installation? Where would we eventually look for the monitored behavior? Would we need some special credentials to access the monitoring panel? […]”

The aforementioned DEM module is part of a broader Federation Monitoring <http://wiki.fi-xifi.eu/Public:Federation_Monitoring#architecture_design> component. If you take a look at its data model, the GE’s deployed at particular VMs are “service” objects. I’m not sure if, in this moment, DEM is collecting information about VM’s services (maybe @Panos could clarify).

Hope this explanation helps.

Best regards.
