Description: Defines managed objects for HTTP proxy and service configuration on Juniper Networks E-series broadband routers.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is Juniper-HTTP-MIB?

Juniper-HTTP-MIB is a Juniper enterprise MIB that manages HTTP daemon/proxy configuration and connection statistics on Juniper E-series broadband routers. It exposes per-daemon configuration (port, access list, same-address connection limit) alongside a rich set of statistics counters covering enabled/disabled sessions, same-host connections, access denials, resource exhaustion, and session creation/removal/aging. Its monitoring value is squarely software-service health: these counters reveal whether the embedded HTTP service is healthy, under load, hitting resource limits (juniHttpDaemonStatsNoResource), or rejecting connections due to access control (juniHttpDaemonStatsAccDeny), which is analogous to monitoring a web server's connection pool. It is a self-contained enterprise MIB layered on the router's internal HTTP service rather than a standard IETF module. It is deployed on Juniper E-series routers that expose an embedded HTTP interface for subscriber or management access. Engineers can download the Juniper-HTTP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Juniper-HTTP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Juniper E-series broadband router

Monitoring Examples

An administrator polls juniHttpDaemonStatsEnabled versus juniHttpDaemonStatsDisabled to gauge how many HTTP sessions are currently active against juniHttpDaemonSameAddressLimit, and watches juniHttpDaemonStatsNoResource for signs of the daemon running out of connection resources. A rising juniHttpDaemonStatsAccDeny counter alongside a configured juniHttpDaemonAccessListName suggests clients are being blocked by policy, while juniHttpDaemonStatsAged shows how many sessions are being reaped due to inactivity. Comparing juniHttpDaemonStatsCreate against juniHttpDaemonStatsRemove over time indicates whether session churn is normal or indicative of a connection leak.

What Can Be Monitored

HTTP daemon enabled/disabled session counts
same-host connection counts
access-list denial counts
resource exhaustion events
session create/remove/aging counts
configured daemon port and access list

How to Use in IPNetwork Monitor

Example using juniHttpDaemonStatsEnabled OID:

Select a Juniper E-series broadband router (embedded HTTP daemon/proxy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type juniHttpDaemonStatsEnabled into the Find box to locate it in the OID tree, then select it and click OK. It reports the count of the number of times the server has been enabled. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
