  • 1.  About the 128T router process

    Posted 02-10-2021 01:31
    When I ran the ㎰ command on the commercial router to check the memory usage of the processes, the following processes were at the top.
    What do these processes do in the 128T router and what effect do they have?

    root 2812 2571 2 273992 281516 3 Jan27 ? 08:39:55 /usr/bin/influxd -config /etc/128technology/influxdb/influxdb.conf

    1. Influx is a time-series database that the 128T uses for storing statistics, metrics, and for producing analytics. The charts you see in the Conductor's UI are rendered based on data stored in Influx. This is third-party software written by InfluxData:
    2. persistentDataManager is a 128T-authored application that handles configuration. It is responsible for validating configuration, generating configuration (when applicable), distributing it from conductor to router, and committing it.
    3. Zookeeper is a third-party database that is used to store state information (e.g., interface state, and alarm state), leadership information (e.g., which node in a router has an active shared interface, which node has the active routingManager). Zookeeper is an Apache project:

    Thank you for your answer.
    I would like to continue asking you and would like to know what the following process is about.

    1. /usr/sbin/road-runner
    2. /usr/lib/systemd/systemd-journald

    I look forward to your reply.

    Item1 is no longer being used and in the process of being deprecated and is custom to the SSR.
    Item2 is a standard Linux process used to collect and manage OS logs. Here is my go to page for any details in regards to "journald":
