Few days ago I checked this website with Qualys SSLlabs test tool and it scored merely a B, so I decided to raise it.

Currently I’m working with big data sets on Graylog + Elastisearch deployments, it runs smoothly when everything is fine, but dealing with backups/snapshots and maintenance tasks is complicated.

My RHCSA is expiring in a few months and I decided to advance a step in Red Hat’s certification path.

On last post I added traefik to my monitoring lab in order to use it as a reverse proxy.

What’s traefik? Quoting verbatim it’s own definition: Traefik is an Edge Router, it means that it’s the door to your platform, and that it intercepts and routes every incoming request: it knows all the logic and every rule that determine which services handle which requests (based on the path, the host, headers, and so on …).

My last weekend’s self-training exercise was about Monitoring Docker containers with cAdvisor, prometheus and grafana, and prometheus has its own persistence layer based on TSDB files, this model is easy to understand, but also has its drawbacks: taking care of replication, backup and availability has to be handled at file lever.

Yes, you are right, this is jamdcwcpg (just another monitoring docker containers with cAdvisor, prometheus and grafana) blog entry, and yes, Internet is full of them and I read almost everyone available in English, maybe I should write it also in Spanish because there are fewer than in English.

Happy new year folks! It’s been three weeks since my last post, I’ve to recognize I took some days off for Christmas.

Today was quite different, I changed my self-studying sessions for a most effective one, I enrolled on a Hands on workshop & lab (HOWL) from RedHat’s devnation program.

Once cerebro is up and running, I wanted to connect it to an elasticsearch cluster and it was also a good opportunity to try out the elasticsearch operator for kubernetes.
