Real-Time Cisco & Palo Alto Dashboards

I am looking for an OpenSearch specialist to build three high-performance NOC dashboards for a network infrastructure environment. We currently have logs from Cisco ISR Routers, Cisco C9200 Core Switches, and Palo Alto 460 Firewalls successfully ingesting into an OpenSearch cluster. The entire stack (Fluent Bit and OpenSearch) is running on Rocky Linux as Docker containers.

The goal is to transform raw log data into actionable, "at-a-glance" visualizations designed for a Network Operations Center (NOC). You must have experience parsing network-specific fields (Syslog/NetFlow/Security events) to create meaningful views.

Key Deliverables:
Dashboard 1 (Connectivity & Health): Visualizing Cisco ISR and C9200 health (uptime, interface status, CPU/Memory spikes, and link flaps).

Dashboard 2 (Traffic Analysis): Top talkers, bandwidth utilization per interface, and protocol distribution based on switch and router logs, router VPN status..
Dashboard 3 (Security & Perimeter): Palo Alto 460 specific views including blocked threats, top source/destination IPs, and VPN session activity.
Required Skills:
Expertise in OpenSearch Dashboards (creating visualizations, saved searches, and complex filters).

Deep understanding of Fluent Bit configuration (parsers, filters, and Lua scripting if needed for field normalization).

Familiarity with Cisco iOS and Palo Alto PAN-OS log formats.

Experience with Docker and Linux (Rocky/RHEL) environments.
