rrdtool 1.7.2-4ubuntu5 (s390x binary) in ubuntu lunar

 The Round Robin Database Tool (RRDtool) is a system to store and display
 time-series data (e.g. network bandwidth, machine-room temperature,
 server load average). It stores the data in Round Robin Databases (RRDs),
 a very compact way that will not expand over time. RRDtool processes the
 extracted data to enforce a certain data density, allowing for useful
 graphical representation of data values.
 .
 RRDtool is often used via various wrappers that can poll data from devices
 and feed data into RRDs, as well as provide a friendlier user interface and
 customized graphs.
 .
 This package contains command-line programs used to access and manipulate
 RRDs.
