J-Insight Device Monitor Basic Configuration

Before You Begin

J-Insight requires that your Junos OS device supports the Junos Telemetry Interface (JTI). For information about JTI, see the Junos Telemetry Interface Feature Guide. To use J-Insight, you must first complete the following steps:

Install the Junos OS Release 18.2R1 or later Junos Network Agent software package. For information on how to install Junos Network Agent, see Installing the Network Agent Package (Junos Telemetry Interface).
Use the show version | grep “na telemetry” command to verify that the Network Agent package was successfully installed.
user@host> show version | grep “na telemetry”
```
JUNOS na telemetry
[18.2|20180508_0022_builder]
```
Install the Junos OS Release 18.2R1 or later OpenConfig for Junos OS software package. For information on how to install OpenConfig for Junos OS, see Installing the OpenConfig Package.
Use the show version | grep “openconfig” command to verify that the OpenConfig package was successfully installed.
user@host> show version | grep “openconfig”
```
JUNOS Openconfig
[0.0.0|20180503_1001_rbu-builder]
```
Use the following commands to configure the Junos Telemetry Interface to accept client connections for gathering sensor data:
- user@host> show configuration system services extension-service | display set
- user@host> set system services extension-service request-response grpc skip-authentication
- user@host> set system services extension-service notification allow-clients address 0.0.0.0/0

Use the show agent sensors command to verify whether or not J-Insight has successfully subscribed to sensors on which it is dependent.

user@host> show agent sensors

J-Insight Health Monitoring

Starting with Junos OS Release 18.2R1, J-Insight supports health monitoring for FPC FRUs on the MX Series routers. The J-Insight health monitor is disabled by default.

To enable the J-Insight health monitor:

user@host# set services jinsightd subscribe health-monitor

To disable the J-Insight health monitor:

user@host# delete services jinsightd subscribe health-monitor

To display the J-Insight health monitor results:

user@host> show system health-monitor [fpc fpc-slot slot-number]

J-Insight Fault Monitoring

Starting with Junos OS Release 18.2R1, J-Insight supports fault monitoring for FPC FRUs on MX Series and PTX Series.

CONFIGURATION COMMANDS

To configure and modify error thresholds and actions at the chassis level:

user@host# set chassis error error-severity threshold threshold-number action recovery-action

To configure and modify error thresholds and actions at the FPC level:

user@host# set chassis fpc slot-number error error-severity threshold threshold-number action recovery-action

Faults in J-Insight can be tracked through syslog and trace options for efficient troubleshooting. To enable J-Insight trace options:

user@host# set services jinsightd traceoptions flag trace-option

CLEAR COMMANDS

To clear a specific error denoted by the error ID URI for a specific FPC:

user@host> clear system errors fpc fpc-slot slot-number error-id error-id- uri

To clear all system errors for a specific FPC:

user@host> clear system errors fpc fpc-slot slot-number all

SHOW COMMANDS

To display information about the conditions that have been configured to trigger alarms:

user@host> show chassis alarms

To display information about the active errors based on FPC, error scope, or error category:

user@host> show system errors active[ fpc-slot slot-number] [detail [scope error- scope [category error-category]]

To display a summary of the number of detected errors and recovery actions taken based on severity level:

user@host> show system error count

To display information about the detected errors based on the FRU:

user@host> show system errors fru [detail] [fpc [fpc-slot slot-number] [ error-id error-id-uri]]
