Prometheus 2 time series database (TSDB) is an amazing piece of engineering, offering a dramatic improvement compared to “v2” storage in Prometheus 1 in terms of ingest performance, query performance and resource use efficiency. As we’ve been adopting Prometheus 2 in Percona Monitoring and Management (PMM), I had a chance to look into the […]Read more
A few months ago I wrote a blog post on How to Capture Per Process Metrics in PMM. Since that time, Nick Cabatoff has made a lot of improvements to Process Exporter and I’ve improved the Grafana Dashboard to match.
I will not go through installation instructions, they are well covered in original blog post. This […]
In my previous blog post, I showed how to deploy Percona Monitoring and Management (PMM) on Linode manually. It is pretty simple, but with a little coding it can be done even more easily using StackScripts
1. Click on the “Add a Linode” and pick a Linode type you want to deploy.
2. Click on the deployed […]
In his excellent blog post, Pavel Trukhanov showed the value of S.M.A.R.T. metric collections, so I wondered how hard would it be to enable their collection in Percona Monitoring and Management (PMM)
A quick search led me to the text_collector plugin SmartMon, which can be easily integrated with any Prometheus Installation
For PMM, Vadim Yalovets recently showed how […]
Please join Percona’s CEO, Peter Zaitsev as he presents Choosing the Right Open Source Database on Wednesday, September 5th, 2018 at 11:00 AM PDT (UTC-7) / 2:00 PM EDT (UTC-4).
The world of open-source databases is overwhelming. There are dozens of types of databases – relational DBMS, time-series, graph, document, etc. – not to mention the dozens […]
One of the common ways to classify database workloads is whether it is “read intensive” or “write intensive”. In other words, whether the workload is dominated by reads or writes.
Why should you care? Because recognizing if the workload is read intensive or write intensive will impact your hardware choices, database configuration as well as […]

When deployed through Docker Percona Monitoring and Management (PMM) uses environment variables for its configuration
For example, if you want to adjust metrics resolution you can pass
-e METRICS_RESOLUTION=Ns as an option to the
docker run command:
docker run -d \
-p 80:80 \
–volumes-from pmm-data \
–name pmm-server \
–restart always \
In Percona Monitoring and Management (PMM) 1.13 we have adopted Prometheus 2, and with this comes a dramatic improvement in resource usage, along with performance improvements!
What does it mean for you? This means you can have a significantly larger number of servers and database instances monitored by the same PMM installation. Or you can […]
