Adding Logos in Zimbra

In Zimbra, there are two different images to re-brand: one is the image that appears in the Login window and the other is the image in the top-left corner when you are logged in. Each image has a different size, and the logos for the open source email platform (FOSS) should be set to the following max sizes:

Installing and configuring cacti on ubuntu to monitor the network

In a recent article, http://“https://blog.renu.ac.ug/index.php/2020/06/17/using-Cacti-to-monitor-your-bandwidth-consumption/”, we learnt how to monitor bandwidth consumption using Cacti and the assumption was that your service provider had given you access to their own Cacti tool which they use to monitor your consumption.

In this article, we shall learn how to install and configure Cacti on your own server either on premise or in the cloud.

Our installation focus is going to be on Ubuntu though it could also be installed on Windows which requires installation of a lot more software as compared to Linux. If you want to install on windows use the link below,

With your own Cacti you will be able to monitor not only the bandwidth consumption but also the state (up or down) of your devices and how long they have been in that state.

Using cacti to monitor bandwidth consumption

Cacti is a free network graphing tool that is used to visualize the time series data obtained by the Round-Robin database tool (RDD tool).

The tool polls network devices like switches and routers via SNMP and then graphs their data. Some of the data that are polled are CPU load, temperature, uptime and network bandwidth utilization.                                                                                                                                        

Here we shall focus on how you can monitor your bandwidth from the cacti graphs.
