When a severe alert pops up indicating server disk utilization hits 92%, traditional O&M follows a time-consuming, cumbersome fixed workflow:

O&M engineer logs into bastion host → runs disk inspection commands one by one → checks occupied files directory by directory → screens deletable files → executes deletion manually.

This process drains massive manpower, and after-hours emergency alerts are a constant headache for O&M staff.

However, in real-world deployment scenarios where Lerwee Agentic Ops connects with WorkBuddy, the entire troubleshooting workflow is fully transformed. Relying on a 5-layer native architecture, disk over-utilization faults form a complete O&M closed loop spanning alert perception, root cause analysis, solution selection, automatic execution, post-event review and long-term optimization.

A real disk-full scenario demonstration below illustrates its outstanding efficiency.

Once Agentic Ops receives an alert that disk partition utilization of a certain server exceeds 90%, the alert is directly handed over to WorkBuddy, and the intelligent agent automatically initiates inspection.

First, it remotely logs into the target host and generates a diagnostic report including alert level, status and other core information.

Then AI conducts granular root cause analysis on directory and file occupancy:

Pull overall disk partition metrics: total capacity 7.5G, used 6.8G with utilization reaching 92%, verifying the alert as a genuine fault instead of false positive.

Run directory occupancy statistics to identify high-occupancy directories: /usr, /opt, /var and /home, sorting out the full resource occupancy overview.

After analysis, actionable self-healing solutions are provided.

Solution 1: One-Click Quick Cleanup

The intelligent agent orchestrates secure scripts to auto purge expired temp files under /tmp, outdated logs and software package caches. It also screens files larger than 100MB for manual review by O&M personnel.

After cleanup, disk metrics are recollected to pull utilization down to safe thresholds, with the whole process operable via one click.

Solution 2: On-Demand In-Depth Inspection

To distinguish disposable temp files from core system program files — releasing disk space while avoiding business outages caused by accidental deletion of critical files — users may instruct AI to further analyze subdirectories under /var and /home and output detailed deep file lists.

Upon execution confirmation, fault recovery completes.

After manual confirmation of the cleanup task, WorkBuddy invokes the automated O&M capabilities of Lerwee Agentic Ops to run pre-generated secure cleanup scripts, and outputs clear before-and-after data comparison.

Disk metrics fall back within safe ranges, and the high disk utilization alert is automatically cleared.

Finally, long-term optimization suggestions are delivered.

Beyond resolving the immediate alert, systematic long-term optimization advice is provided to fundamentally reduce fault recurrence risks.

More Than Troubleshooting: Robust AI O&M Capabilities Empowered by Agentic Ops

Single disk fault self-healing is just one use case. Lerwee Agentic Ops underpins WorkBuddy with a full 5-layer underlying architecture that unifies data collection, asset management, business links, knowledge base and automated execution.

5-Layer Native O&M Closed-Loop Architecture: Perception – Memory – Planning – Action – Core Brain

It natively integrates Perseus full-domain collector, CMDB asset library, monitoring/log/APM modules and Lerwee Claw automated execution engine, with built-in professional O&M knowledge graph, RCA root cause analysis, alert convergence, business topology analysis and change control capabilities.

Trustworthy Data Foundation

It stores full-stack original IT metrics, logs, asset topologies, historical fault tickets and execution scripts. It delivers traceable, executable, specification-compliant professional conclusions for upper-layer interaction, eliminating O&M hallucinations common in generic large language models.

Closed-Loop Execution Permissions

It directly triggers server restart, capacity expansion, configuration modification, scheduled inspection, ticket dispatch and self-healing tasks, with complete permission control over enterprise IT infrastructure.

Unified Multi-Channel Portal

Native integration with DingTalk, Lark and WeCom. O&M staff send natural language commands, receive alerts and view reports via chat windows without accessing dedicated O&M dashboards.

Multi-Agent Task Orchestration

Complex O&M demands can be split into sub-agents dedicated to inspection, report generation, change audit and review document drafting, which collaborate to schedule Lerwee intelligent agents for batch and cyclic composite tasks.

Long-Term Memory + Active Push

It records user interaction habits, core business scopes and duty rosters. Daily/weekly reports and fault review documents are auto-generated and pushed regularly. Memory data is synchronized across all channels for consistent session context.

Supplementary General Office Capabilities

Built-in functions for Office document parsing, report generation, PDF review report export and data summarization, converting raw O&M outputs into standardized deliverable documents for internal and external sharing.
