Dear Fabio,

The best way to handle this is to forward this message to
fiware-tech-help at lists.fiware.org

It’s better if you do it because you will get the email notifications on
changes and answers. We will notify the Proton team anyway.

Best Regards,

Sergio.

Hi Sergio,
we have used these few days for performing one more test (VM scaling up).

The main problem, as I said, is that Proton is consuming too much HW
resources while managing only a bunch of alerting rules, which produces or
the app crash or requires the VM restart.

We have tested the entire system in 2 different IaaS installations.

a) GEs used: IDAS IoT Agent 1.3.1. + ORION 0.26.1 + PROTON CEP 3.3.1
b) Installation type: local installation on a IaaS provider
c) Installation method: Docker + Docker Compose

Installations specs:
- 1st installation: 1 VM (14 GB RAM, 4 core) containing the 3
GEs
<-- in this case we haven' seen any problems. It should be said that this
was an initial installation where we implemented only 2 or 3 Proton rules
- 2nd installation - *small size* (due to IaaS provider migration): 1 VM (4
GB RAM, 2 core) containig the 3 GEs  <-- in this case Proton eats up to 1.2
GB of RAM and constantly uses 98% of 2 cores (with 8 Proton rules)
- 2nd installation - *mid-size* (scaling up of the previous VM): 1 VM (8 GB
RAM, 4 core) containing the 3 GEs   <-- Proton still eats up to 1.2 GB of
RAM and constantly uses 3 cores at 100% (with 8 Proton rules)

We don't know where the problem is.
Our dev team thought there was too much messages between Orion and Proton,
that Proton is unable to manage, so they are looking for a workaround, a
method to reduce them. Here is the link to our bug/request:

Thank you for your help
