Introduction
Server statistics is a special page in Alumio where you can find everything that is needed to understand what’s going on with your environment.
You can always find this page via: Settings > Server statistics.
The Server statistics page provides a number of information regarding the disk load and usage, CPU and Mysql Disk usage, Memory usage, Disk inodes and System load points as well.
In this article, we will explain how to work with each component of the Server statistics page and provide some tips as wel.
Disk load
Disk usage graph provides clarity on the disk usage in regards to speed.
In Alumio it’s possible to track the disk load by Disk write time and Disk read time.
Disk write time usually reports the number of gigabytes (GB) busy with servicing write requests (the Y panel of the graph).
Disk read time is used to service read requests and reports the number of GB as well.
You can always track the number of GB by hovering over the special point on the graph and compare investigations between different amounts of time, described on the X panel of the graph.
Besides, you are able to deactivate one of the data types on the graph. To do that, all you need is a simple click on the corresponding data type at the bottom of the graph.
In addition, if you would like to view the disk load through the entire day or period of time, just select the time period at the top of the page. Please, be aware that the nearest log you are able to view on the graph is approximately 1-5 minutes before the current time.
Disk usage
Disk usage graph describes the amount of storage that is currently in use.
On the graph you can see three lines, each of them shows how much GB are in use, GB left and their total size.
That means you can easily track disk usage in the corresponding time window selected on the top of the page.
The general calculation for disk usage is the following:
Disk total size = Disk total free + Disk total usage + cashes.
It’s important to mention, that cashes display with Disk total size automatically.
As usual, you are able to select any timestamp, point on the graph and even remove one of the data types to investigate disk usage.
CPU usage
CPU tracks the percentage of processing power used by various data and tasks within Alumio. On this graph, you can find metrics about CPU Idle, CPU System and CPU User, which help understand better the overall load usage.
As usual, you are able to select any timestamp, point on the graph and even remove one of the data types to investigate CPU usage.
Mysql Disk usage
Monitoring Mysql Disk usage stands for investigation of the amount of GB used by Mysql Mount Disk, Myql Binlog Disk and Mysql Binlog Cache Disk.
As usual, you are able to select any timestamp, point on the graph and even remove one of the data types to investigate Mysql Disk usage.
Memory usage
Memory usage displays usage over time on the graph. It’s possible to track the amount of Total Memory, Free Memory and Memory in Use.
Formula for calculations is the following:
Memory in Use = Total Memory - Free Memory.
Hovewer, Memory in Use includes cached memory.
Memory not being used is memory wasted, that’s why the system will always try to use the maximum amount of memory by creating a bigger cache for example.
As usual, you are able to select any timestamp, point on the graph and even remove one of the data types to investigate Memory usage.
Disk inodes
Disk inodes show the tracking of all files that are in your environment using Inode total size, Inode total free and Inode total usage.
The calculation can be performed via the such formula:
Inode total size = Inode total free + Inode total usage.
As usual, you are able to select any timestamp, point on the graph and even remove one of the data types to investigate Disk inodes.
System load points
System load points indicate reliability and measure the amount of work that the server performs. It’s possible to view the System load points metric presented as curves on the graph.
As usual, you are able to select any timestamp and point on the graph to investigate System load points.
What is Datadog and how it can help?
As you may know at the bottom of each graph you can see the “Generated by Datadog” signature. No need to worry, below you can read what Datadog is and how it can help!
Datadog is a monitoring and analytical tool which enables Alumio to collect all described metrics and display them in real-time. Every meaning of metrics is provided Live and updates every time. You are also able to click on the “Reload graph” to update metrics manually.
Ending note
In conclusion, we have to say that Server statistics is a very useful page where you can find a collection of live metrics which help you understand Alumio better and simplify the entire work.
