Sentry leads on adoption by 1,251% (45,704 vs 3,383 stars). Sentry is written in Python under a custom or non-standard licence; sysstat is written in C under GPL-2.0. Sentry has attracted 11% as many forks as stars, sysstat 15%. Sentry was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (monitoring), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.
