💖 ISAG(1) — the Interactive System Activity Grapher, bestie edition 💖

okay so welcome to the manual page for isag, aka the Interactive System Activity Grapher, from the System Activity Grapher fam. pull up a chair, grab a lil snack, we're gonna make pretty graphs out of your system's whole vibe. 🦋

✨ NAME ✨

isag — Interactive System Activity Grapher. that's it, that's the name, she's iconic and she knows it. 👑

---

🌸 SYNOPSIS 🌸

isag [-p datafiles_path] [-c config_file] [-ght gr_height] [-gwd gr_width]

---

💫 DESCRIPTION 💫

so here's the tea: the isag command graphically displays the system activity data that got stored in a binary data file by a previous sar run. no cap. and the way it does that? it literally invokes sar to extract the data that's gonna be plotted. teamwork makes the dream work fr fr. 🫶

then the data gets processed using the sar command and slightly transformed into tabular format, and after that this format is visualized using the gnuplot program. so it's giving pipeline, it's giving glow-up, it's giving graph. ✨

🎀 OPTIONS 🎀

• -p datafiles_path — tell it where the daily data files live, bestie. the pathname where they're located, specifically. default path is: /var/log/sysstat. (yes, that's the default, write it down 📝)
• -c config_file — specify the configuration file used by the isag command. heads up though: the contents of this file may depend on the isag version number. the default config file is: $HOME/.isag.cfg.
• -ght gr_height — set the height of the chart area. default value is: 400.
• -gwd gr_width — set the width of the chart area. default value is: 720.

---

🌈 CONFIG FILE 🌈

as mentioned above (👆 yes, the -c thing), there is a config file. and inside it, the following values are stored:

• last showed graph
• y limits for each kind of graph

and honestly? it seems useful, because a new run doesn't need new settings to obtain the same scale. consistency queen. 💅

---

🧚 PREREQUSITIES 🧚

here's the list of prerequsities, including versioning and built-in features:

• Tcl/Tk Version 8.0 or newer.
• gnuplot
  • Gnuplot must have a tkcanvas display.

⚠️ no tkcanvas display in your gnuplot? then we simply cannot serve the looks, bestie. that's a requirement, not a suggestion. 😭
