nGenius Probes - Key Features
| Application Recognition and Monitoring |
| Support for a variety of application types, including |
- Well-known and children of well-known applications
- User-defined, custom-developed applications
- Complex applications using port-ranging/port-hopping
- Peer-to-peer applications
- Web-based applications and URLs
- Industry specific applications (e.g. IP FIX for financial, SMS for wireless service provider)
|
- Robust packet capture decode engine (450 protocol family decodes)
- Perform four simultaneous packet captures per interface
- Launch packet capture from the user desktop
- Pre-capture filtering
- Supports capture and upload to nGenius Performance Manager
- Configure a data capture to start automatically by matching a pattern of packets
|
| Response Time Analysis / Key Performance Indicators |
- Passive application responsiveness measurements
- Supports response time metrics for virtually all application types
- Supports 1-minute granularity: average response time, no. of active sessions, no. of successful transactions, and no. of server error types
- Supports 15 minute granularity: maximum & average response time per client/server pair, total no. of transactions, no. of successful transactions, TCP connect time, no. of active sessions, total packet loss, responses time distribution, no. of timeouts, no. of retries, and application payload
- Measures key performance indicators including packet loss, inter-packet delay, client and server errors, and timeouts
|
- Supports volume, utilization, host and conversation details for RTP Voice and RTP Video protocols
- Supports application-layer details for call set-up protocols, such as SIP, H.323, Q.931 and MGCP, plus Cisco's SCCP and Avaya's H.323 extensions
- Supports VoIP quality metrics: jitter, call set-up time, packet loss, incomplete and failed calls, and MOS scores
- Supports IP addresses, phone extensions and connect times
- Supports packet-level visibility and decode of voice protocols
- Supports voice configuration data including Codec, dialing plan and QoS assignments
|
| Network Management Metrics |
- TCP, HTTP and server-specific performance and error conditions
- Percent Utilization and Packet/Byte Counts for: link, host, host group, applications, conversations
- Link aggregation combines traffic data from multiple interfaces to support load balanced and redundant links
- Site monitoring tracks traffic from remote offices
|
| Alarming and Event Identification |
- Define alarms for link utilization, CRC errors, application utilization, application response time, application availability as well as broadcast packets, multicast packet and multicast packets on the LAN
- Burst Alarms at millisecond resolution
- “Power Alarms” highlight root cause by gathering top users and applications automatically at violation time for segments exceeding utilization, responsiveness and availability thresholds
- Supports rising, falling and time-over-threshold templates
- Supports auto-actions to trigger scripts, packets decode and SNMP traps
|
- 15-second, real-time views with 1-second peaks
1-minute historically logged data for all application, hosts, and conversation flows
|
- LAN – Fast Ethernet, Gigabit Ethernet, 10-Gigabit Ethernet
- WAN – Frame Relay (T1/E1, T3(DS3)/E3), ATM - (T3(DS3)/E3, OC-3c, OC-12c), POS (OC-3c, OC-12c, OC-48c)
- Virtual Channels – VLANs, DLCIs, PVCs, QoS Groups (via DSCP)
- Encrypted Channels – MPLS, IP-enabled VPN
|
- In-line connection via passive tapping device
- Span via Switch Mirror port for 10/100/1000 Ethernet
|
- Supports 10/100/1000 Ethernet Interface Speeds
