The problem is the compatibility. Our version of Openstack is too old, I'm affraid.
Sorry for the inconveniences, but it won't work.
Regards,
José Ignacio.

Hi Jose,
DEM collects data from the VM metadata and send them to the Context Broker.
For this particular case, we looked at the configuration file and the log file that ENG sent. The conclusions are the following:
1. DEM has been installed correctly (service is running).
2. DEM tries to read data from metadata by issuing (curl http://169.254.169.254/openstack/latest/meta_data.json).
3. The response is the following (according to ENG email, below):
root at finesce-wp4-dev-server:~# curl http://169.254.169.254/openstack/latest/meta_data.json
1.0

From this response, we assume that probably the cause of the problem is that the OpenStack metadata is not enabled on the Spanish node (only EC2 is enabled by default as far as i know). DEM collects no data and so it does not send to the CB.
Best,
Panos.

Θέμα: Re: [Fiware-lab-help] [FINESCE WP4] Trying to use Monitoring GE - OpenStack metadata service to be enabled
Dear Massimiliano,
Can you explain me a bit more what is the problem with the metadata? I think it is working. --
@panos - May I ask what requests does the DEM component send to the metadata server? Does that component requiere a minimun version of (Openstack) metadata server? -- If I knew the queries needed by the component, I would test wheather the Metadata is working or not.
Thank you all,
Best regards,
José Ignacio.

Dear Massimiliano,
I just received the answer to the internal query I sent this morning. The answer is that this is enabled in the Spanish node. Are you talking about a different node?

To whom it may concern,
we would need the Open Stack metadata service to be enabled in order to use the Monitoring GE (as suggested by Panos-Synelixis / Pablo-Telefonica......see a couple of e-mails below).
Please let us know when this will be done.

Sorry for the inconvenience, but some questions need to be clarified:
1) We (TID) are the owners of FIWARE’s Monitoring GEi (the “i” stands for “implementation”). We will be pleased to solve any issue regarding this enabler. Please note that our GEi depends on an existing monitoring tool (for example, Nagios) to monitor the resources, including VMs.
2) Due to several reasons, XIFI (another FI-PPP project related to FIWARE) decided to bypass Nagios or any other monitoring tool for the VMs, and use the DEM module instead: this is Synelixis responsibility and our current recommendation for the monitoring of VMs.
3) In either case, we all depend on the underlying cloud infrastructure (FIWARE Lab) and, particularly, on the OpenStack Metadata Service.
For any issue related to FIWARE Lab Cloud, please refer to http://help.lab.fi-ware.org/. If, as Panos suggests, the metadata service isn’t available, you should open a ticket in FIWARE Lab Support.
Hope this clarifies a little.
Best regards.

Hi Leandro,
Happy new year!
It seems that .
Please see this link: Metadata service - OpenStack Cloud Administrator Guide - current<http://docs.openstack.org/admin-guide-cloud/content/section_metadata-service.html> and especially the section "Run the metadata service".
Also, note that metadata service supports two sets of APIs: an OpenStack metadata API and an EC2-compatible API.
At your disposal for further clarifications.
Best regards,
Panos.

Hi Panos and Pablo,
thanks for your answer.
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 at finesce-wp4-dev-server:~# curl http://169.254.169.254/openstack/latest/meta_data.json

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