classes descriptions about hb_report

class node

The father of master and collector,abstract some common features.

member variable

member function

class master

member variable

NOTE：
1.Suppose this situation, the user is not running hb_report as a root, which is allowed. However,because of the collection of information collected from journalctl,it is necessary as a root user when you need to ssh to the collector node. Therefore, before testing ssh, you need to test the current user. If not the root user, you need to save the switch to the root user command. SUDO save ssh to the collector node when switching the root user command, LOCAL_SUDO save the master node to switch to the root user The command
2.Yes, even in the master node, wo still use class collector to clollect log.

member function

NOTE：
1.Start_collect function just do some check stuff and create subprocess(if ssh doesn't need password) ssh to collector node run collector script collect.This is the way to collect collector node log, for the master node, create collector instance then collect log
2.If cluster node need ssh password, then cannot create the new process collect log.
3.ENVIRONMENT member variable is the class envir instance,assign value in the master class,then use function send_envir create xml file send the ENVIRONMENT to collector node
4.Class master_node init function have one parameter——class envir instance

class collector

member variable

member function

NOTE：
1.In order to reduce the network pressure,the result return from collector node is tarball
2.Master node ssh to collector node,then run the collector script

class envir
