Admin Tasks / Devops

This page rpovides afew examples of admin/devops related commands.

Ascon

Use ascon tool to establish direct admin connection to the process via TCP (no webserver needed).

# if you do not supply password inline, the tool will prompt you for it
$ ascon myserver1:7797 -c id=root pwd="your-password"

Manc

Get a list of components

  manc

Get a list of commands that component understands

  manc{ sid=123 call-list{}}

Dctl

Dctl allows to control daemons. Use manc to get desired component SID

> dctl{sid=123 action=stop};
> dctl{sid=123 action=start};

Mongo Db management

Mongo db connector understands directdb component command. It is used for general mongo management and usefull for Chronicle and Minidp management as well.

Assuming that manc returned sid=123 for "Connector.MongoClient"

Get Chronicle Record Count

Connect to memoir admin console

Then run:

manc
{
  sid=123 // use manc to lookup your component sid
  call
  {
    directdb
    {
      s='mongo://localhost:27017'
      d='sky_chron'
      cmd='{count: "sky_log"}'
    }
  }
}

Fetching records

Connect to memoir admin console

Then run:

manc
{
  sid=123 // use manc to lookup your component sid
  call
  {
    directdb
    {
      s='mongo://localhost:27017'
      d='sky_chron'
      cmd='{find: "sky_log", limit: 3}' //build query here
    }
  }
}

Create indexes

Connect to memoir admin console

You need to create Chronicle indexes in mongo so queries do not take long time.

Refer to this: https://docs.mongodb.com/manual/reference/command/createIndexes/

The following exmaple creates an ascending non-unique index on chronicle field u:

manc
{
  sid=123 // use manc to lookup your component sid
  call
  {
    directdb
    {
      s='mongo://localhost:27017'
      d='sky_chron'
      cmd=$'{createIndexes: "sky_log", indexes: [
       {
         key: {u: 1}, //field name 'u' for utc time stamp
         name: "idx_utc",
         unique: false       
       }
      ]}'
    }
  }
}

Delete old Chronicle log data

Connect to memoir admin console

The delete query would work well when u field is indexed as described above.

manc
{
  sid=123 // use manc to lookup your component sid
  call
  {
    directdb
    {
      s='mongo://localhost:27017'
      d='sky_chron'
      cmd=$'{
        delete: "sky_log", 
        deletes: [
         {
          limit: 1,//this can be either zero or 1 to delete a single document
          q: {u: {"$lt": "mm/dd/yyyy"}}
         } 
        ]}'
    }
  }
}

Bash curl loop through files

#!/bin/bash

for file in /this/is/my/path/example*
do
  curl -X POST -T "/this/is/my/path/$file"  https://whatever
done;
