\caption{Task event rates vs.\ task priority and task termination in 2011 and 2019 (all clusters aggregated) traces. For 2019 traces tier classes instead of raw priority values are shown: 2011's $[0,1]$ priority range corresponds to the ``Free'' tier, range $[2,8]$ corresponds to the ``Best effort batch'' tier, range $[9-10]$ corresponds to the ``Production'' tier and priority 11 corresponds to the ``Monitoring'' tier.}\label{fig:figureVII-a}
\caption{Task event rates vs.\ event execution time and final task termination in 2011 and 2019 (all clusters aggregated) traces. Execution time classes are defined in minutes, with the exception of ``1d'' which means one day.}\label{fig:figureVII-b}
\caption{Task event rates vs.\ event execution time and final task termination for each cluster in the 2019 traces. Refer to figure~\ref{fig:figureVII-b} for interpretation of the execution time classes.}\label{fig:figureVII-b-csts}
\caption{Task event rates vs.\ machine concurrency and final task termination in 2011 and 2019 (all clusters aggregated) traces. Machine concurrency is defined as the number of co-executed tasks on the machine where the analyzed task is executing.}\label{fig:figureVII-c}
\caption{Task event rates vs.\ machine concurrency and final task termination in each 2019 cluster. Refer to figure~\ref{fig:figureVII-c} for the definition of ``machine concurrency''.}\label{fig:figureVII-c-csts}
