CPU / Memory Triage

Multi-device CPU/memory crisis triage: process-level analysis, spike correlation with network events, memory pool health, EEM/alarm history, and automatic remediation suggestions.

Auto remediation hints

Required inputs

Parameters the script accepts. Defaults shown; some are vendor- or context-gated.

Parameter	Type	Default	Notes
CPU alert threshold (%) cpu_threshold	number	80	—
Mem alert threshold (%) mem_threshold	number	85	—
Top N processes to show top_processes	number	10	—
Include EEM alarm history check_eem	bool	true	—

Hint 1 — Name your vendors and OS versions

Mention the exact platforms you run (Cisco IOS/XE/XR/NX-OS, Juniper, Arista) so the generated analysis logic uses the right CLI/NETCONF syntax.

Hint 2 — State your real thresholds

Provide concrete values for CPU alert threshold (%), Mem alert threshold (%), Top N processes to show instead of the defaults — they shape what counts as a fault.

Hint 3 — Prioritize the checks you need

This tool can top-N process CPU drill-down and memory pool analysis. Ask for the subset relevant to your incident to keep output focused.

Hint 4 — Describe your inventory format

Tell the assistant whether your device list is CSV, YAML, or JSON and which columns it has, so parsing matches your data.

Sample inventory schema

Authoritative shape of the device/policy data this script consumes.

No bundled inventory sample. The script accepts standard device lists (CSV/YAML) with hostname, mgmt IP, vendor, and credentials.

Expected output

Reference terminal output the script should produce — used as a stylistic and structural target.
