We are looking for install here, at the office, a “central” Graylog.
Outside, by some of our customers, we have to collect informations but in a small scale each time. Our problem is that the communication between the customer and our office fall down, we loose all the datas.
To prevent this, I’m asking me if Gaylog installed on a Raspberry PI3 by the customers could’nt be an interesting solution, not just because of the costs, but also for the small place needed by a Raspberry.
Graylog could be deployed on a RPi 3, but with limited performance.
I never tested that, so my answer would be: Try it and report about it.
Little hint: The RPi has limited memory. Make sure that you limit Graylog and Elasticsearch in their memory usage to fit into the memory of the RPi (while leaving some space for the OS itself)
Hey @derPhlipsi and thank’s for your so fast answer !
We ar collecting datas from programmable logic controllers and the information string is very short : [{"tag":"DO_SIMU[199].1","value":"False","time":"2018-09-05T14:35:09.1189226+02:00"}] for example.
The logical architecture we have is quite simple.
The material architecture is also easy, Micro SD cards can go up to 400Gb.
Of course, the Rasp 3 is shot in memory but I’ld really be interested to test Graylog on such a machine
the main problem will be that you find the option to run elasticsearch 5.x on the rpi AND Graylog at the same time. You need to look at the memory settings for the JVM (as @derPhlipsi already wrote)
But we would like to hear your story - success or not.
