Pegasus Monitor 1.2.1 (Build 4) — Server uptime

• Display Linux server uptime beneath each server's health count in the menu-bar server list.
• Show an Uptime row in the selected-server overview.
• Use compact days, hours and minutes; for example 12d 4h 8m.
• Include uptimeSeconds in JSON from both server/remote-health-json and server/pegasus-health-json, obtained from /proc/uptime without elevated privileges.
• Remain compatible with older monitoring agents: uptime shows Not available until the agent is updated.
• Preserve 1.2.0 service discovery, required service rules, configuration, signing and notarization scripts.

Deploy the updated agent

For ordinary Ubuntu/Debian servers:

scp server/remote-health-json USER@HOST:/tmp/pegasus-monitor-health-json
ssh USER@HOST 'sudo install -m 755 /tmp/pegasus-monitor-health-json /usr/local/bin/pegasus-monitor-health-json'

For Pegasus's specialised agent:

scp server/pegasus-health-json mag@192.168.1.2:/tmp/pegasus-health-json
ssh mag@192.168.1.2 'sudo install -m 755 /tmp/pegasus-health-json /usr/local/bin/pegasus-health-json'

Keep the original SSH command configuration for each server. Refresh the Mac application after agent updates.
