Network Management and Monitoring

  • Support for multiple gRPC servers hosting different service sets (EX2300, EX2300-C, EX2300-MP, EX2300-VC, EX3400, EX3400-VC, EX4000-8P, EX4000-12P, EX4000-12T, EX4000-12MP, EX4000-24MP, EX4000-48MP, EX4000-24P, EX4000-24T, EX4000-48P, EX4000-48T, EX4100-24MP, EX4100-24P, EX4100-24T, EX4100-48MP, EX4100-48P, EX4100-48T, EX4100-F-12P, EX4100-F-12T, EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, EX4100-F-48T, EX4100-H-12MP, EX4100-H-12MP-DC, EX4100-H-24F, EX4100-H-24F-DC, EX4100-H-24MP, EX4100-H-24MP-DC, EX4300-MP, EX4300VC, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48MXP, EX4400-48P, EX4400-48T, EX4400-48XP, EX4600-VC, EX4650, EX4650-48Y-VC, EX9204, EX9208, EX9214, MX204, MX240, MX304, MX480, MX960, MX2008, MX2010, MX2020, MX10004, MX10008, cSRX, SRX300, SRX320, SRX340, SRX345, SRX380, SRX1500, SRX1600, SRX2300, SRX4100, SRX4200, SRX4300, SRX4600, SRX4700, SRX5400, SRX5600, SRX5800, and vSRX 3.0)—You can configure multiple gRPC servers that host different sets of services on unique ports. Additionally, each server can support different certificates, listening addresses, and routing instances. You configure the gRPC servers at the [edit system services http servers] hierarchy level. Distributing gRPC services across different servers allows for better allocation of network resources, reducing the risk of port conflicts and optimizing server performance.

    [See Configure gRPC Services and server.]

  • SNMP support for coherent ZR optics performance monitoring and threshold alerts (MX204, MX240, MX304 with MX304-LMIC16-BASE line card; MX480, MX960, and MX10003; MX10004, MX10008, MX10016 with MX10K-LC9600 line card; and MX2008, MX2010, MX2020 with MX2K-MPC11E line card)—You can monitor the performance of coherent ZR optics (100ZR, 400ZR, 400ZR-M, and 400ZR-M-HP) and receive threshold crossing alerts by using SNMP. Retrieve real-time, historical, and statistical data for various performance parameters through SNMP get-requests. You also can receive trap notifications for threshold crossing alerts and clear events.

    Use the updated enterprise MIB named Juniper-IFOPTICS-MIB to comprehensively monitor and manage coherent ZR series transceivers.

  • Enhanced on-box memory monitoring with configurable thresholds and improved alarm validation (EX2300-C, EX3400, EX4100-24P, EX4100-24T, EX4300-MP, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-48MP, EX4650, MX960, MX10003, MX10004, MX10008, MX10016, MX2008, MX2010, MX2020, SRX2300, SRX4200, SRX4300, SRX4600, SRX4700, and SRX5800)—You can monitor system free pages and excessive swap memory usage more efficiently to prevent memory shortage issues. The enhanced validation process reduces false alarm triggers.

    Additionally, you can set user-configurable thresholds to monitor the Virtual Memory Size (VSZ) of processes, with events categorized based on severity. Use the set system monitor memory process minor/major/critical-event threshold process-name memory-limit configuration statement to configure these thresholds.

    The system integrates alarms with the eventd and alarmd infrastructure, enabling you to view the alarms using the show system alarms command.

    Use the show system monitor memory events all and show system monitor memory status all commands to view all recorded events and the latest status on memory usage.
