This is part of what makes the AXE Ninja monitoring application. It contains:

• axe-node.php : is a php implementation of Axe protocol to retrieve subver during port checking
• axeblocknotify : is the blocknotify script (for stats)
• axeblockretrieve : is a script used to retrieve block information when blocknotify script did not work (for stats)
• axeupdate : is an auto-update axed script (uses git)
• dmnbalance : is the balance check script (for stats)
• dmnblockcomputeexpected : is a script used to compute and store the expected fields in cmd_info_blocks table
• dmnblockdegapper : is a script that detects if blocks are missing in cmd_info_blocks table and retrieve them if needed
• dmnblockparser : is the block parser script (for stats)
• dmnctl : is the control script (start, stop and status of nodes)
• dmnctlrpc : is the RPC call sub-script for the control script
• dmnctlstartstopdaemon : is the start/stop daemon sub-script for the control script
• dmncron : is the cron script
• dmnportcheck : is the port check script (for stats)
• dmnportcheckdo : is the actual port check sub-script for the port check script
• dmnreset : is the reset .dat files script
• dmnthirdpartiesfetch : is the script that fetches third party data from the web (for stats)
• dmnvotesrrd and dmnvotesrrdexport: are obsolete v11 votes storage and exported (for graphs)

Requirement:

• AXE Ninja Back-end: https://github.com/axerunners/axeninja-be
• AXE Ninja Database: https://github.com/axerunners/axeninja-db
• AXE Ninja Front-End: https://github.com/axerunners/axeninja-fe
• PHP 5.6 with curl

Important: Almost all the scripts uses the private rest API to retrieve and submit data to the database (only dmnblockcomputeexpected uses direct MySQL access).

Install:

• Go to /opt
• Get latest code from github:

git clone https://github.com/axerunners/axeninja-ctl.git

• Get sub-modules:

cd axeninja-ctl
git submodule update --init --recursive

• Configure the tool.

Configuration:

• Copy dmn.config.inc.php.sample to dmn.config.inc.php and setup your installation.
• Add dmncron to your crontab (every minute is what official AXE Ninja uses)

*/1 * * * * /opt/axeninja-ctl/dmncron

If you want to enable logging, you need to create the /var/log/dmn/ folder and give the user write access. Then add "log" as first argument when calling dmncron:

*/1 * * * * /opt/axeninja-ctl/dmncron log

• Add dmnthirdpartiesfetch to your crontab (every minute is fine, can be longer)

*/1 * * * * /opt/axeninja-ctl/dmnthirdpartiesfetch >> /dev/null

axeblocknotify:

• You need /dev/shm available and writable.
• Edit axeblocknotify.config.inc.php to indicates each of your nodes you wish to retrieve block info from.
• You can either retrieve block templates (bt = true) and/or block/transaction (blocks = true). For the later you need to have txindex=1 in your axe config file.
• Add in each of your nodes in axe.conf a line to enable blocknotify feature:

blocknotify=/opt/axeninja-ctl/axeblocknotify

• Restart your node.
• On each block received by the node, the script will be called and data will be created in /dev/shm.
