Save dataset stats

[peppocola]

I need to fill this table about the dataset.

\begin{table}[t]
\centering
\caption{Temporal segmentation summary for selected ecosystems.}
\label{tab:temporal-slices-summary}
\resizebox{\linewidth}{!}{%
\begin{tabular}{rrrr}
\toprule
\textbf{Ecosystem} & \textbf{Training Months} & \textbf{Test Months} & \textbf{Training Instances} \
\midrule
Apache & \texttt{51} & \texttt{XXX} & \texttt{XXX} \
Jira & \texttt{59} & \texttt{XXX} & \texttt{XXX} \
RedHat & \texttt{57} & \texttt{XXX} & \texttt{XXX} \
\bottomrule
\end{tabular}%
}
\end{table}
I need a script that calculates, based on the configs for months (m1 in the name e.g. config-apache-m1.yaml), how many train, test months are there and how many are the training and testing instances.
