This page contains some basic information about my two servers:
thalia. You can click on the plots to enable mouse tracking. If you click on the legend you can toggle the visibility of the datasets and if you click on the grid icon (in the lower left corner) you can toggle the visibility of the background grid.

§3 Load Averages Plot
§4 Temperatures Plot
§5 Disk Usage Plot
The orange region shows the theoretic limit of
clio’s storage capacity and the red shows the same for
§6 Firewall Denials Plots
Note the logarithmic axes.
This second plot probably requires some explanation. In purple I have plotted, as points, the number of denials in a day on
clio against the number of denials in the same day on
thalia to study if there is any correlation in the denial rate at a given time on the two servers. The purple line is the linear fit to the dataset and Pearson’s correlation parameter is written in the top-right corner in purple too. As of March 2018 they appear to be un-correlated. Additionally, in red and blue, I have plotted the histograms of the denials on
thalia respectively. Finally, I have written some basic parameters on the plot, such as the mean and the median values, to demonstrate that eventhough the denial rates at a given time on
thalia are un-correlated their distributions are nonetheless broadly similar.
§7 Firewall Denials Maps
These maps are created using locations provided by freegeoip.net. Note the logarithmic axes.
§8 Firewall Denials "Country Of Origin" Table
This table is created using locations provided by freegeoip.net.
§9 Network Plots
In the first plot: green indicates full network access; orange is only local network access; and red is no network access at all. Note the logarithmic axes in the second and third plots.
This third plot also probably requires some explanation. In purple I have plotted, as points, the receiving network rate on
clio against the sending network rate on
thalia at the same time to study if there is any correlation in the network rates at a given time on the two servers. (There should be as
clio is the slave and
thalia is the master). The purple line is the linear fit to the dataset and Pearson’s correlation parameter is written in the top-right corner in purple too. As of March 2018 they appear to be correlated.
§10 Bandwidth Plot
As mentioned above,
clio is the slave server therefore the rate of data creation is indicative of the bandwidth of the connection from
clio (give or take compression). Note the logarithmic axes. As of May 2019, the modal value is 9.5 Mb/s which equates to 1.13 MiB/s: this results in 3.98 GiB/hour and 1 TiB is transferred in 10.7 days. As of May 2019, the ISP of the connection that
thalia uses thinks that the upload speed is 12.0 Mb/s which equates to 1.43 MiB/s: this results in 5.03 GiB/hour and 1 TiB is transferred in 8.5 days.
