Estimating server disk space availability using the Zabbix API

Code GitHub location .

Main function: Get all the machines under a Zabbix, calculate how many days the remaining disk space of these machines can be used according to "natural" growth.

Main process:

1. Get all the machines under a group.

       def host_get_by_groupid (self,groupid):         data = json.dumps (                 {                      "Jsonrpc":  "2.0",                      "Method":  "Host.get",                      " Params ": {                          "Output": "Shorten",                          " Groupids ": Groupid,                         },                      "Auth": self.authid,                      "id": 1,                 })          res = self.get_data (data) [' Result ']

2. The

   Gets the remaining space on the disk for these machines at some point in the historical X-day time.

       def history_get (Self,itemid,time_from):         data = json.dumps (                 {                      "Jsonrpc":  "2.0",                      "Method":  "History.get",                       "params": {                          "Itemids": [itemid],                           "Time_from":  time_from,                          "Output":  "Extend",                          " SortOrder ": " ASC ",                          "Limit":  "1"                           },                      "Auth": self.authid,                      "id": 1                  })         res = self.get_data (data) [' Result ']        log.debug (res)          if  (res != 0)  and  (len (res)  == 1):             return res[0]         else:            return {"Value":-1, " Clock ": Time_from}

4. Use 2 of the data to calculate the daily decrease value, remove the 2 maximum, and use these positive values for an average if decrease is a positive number for more than half days.

   #if The decrease if more than increase, maybe they has a crontab to relase space. #like this 5 4 5 4 5 4

6. The current remaining space/average to get the final result.

Objective:

1. Master the use of Python to access the Zabbix API.

2. In order to more "realistic" to do capacity planning.
