最近发现一篇文章《使用zabbix api创建screen》,然后下载脚本进行测式,发现二个问题:
1. 不支持3.x版本。
2. 添加的screen的主机名称不是按顺序排列,不方便查询。
便自己修改了一下,让支持zabbix3.x版本,并输出的screen(聚合图形)按机器名称排列。
#!/bin/env python import json import urllib2 import argparse import re re_digits = re.compile(r‘(\d+)‘) def emb_numbers(s): pieces=re_digits.split(s) pieces[1::2]=map(int,pieces[1::2]) return pieces def sort_strings_with_emb_numbers2(alist): return sorted(alist, key=emb_numbers) def requestjson(url, values): data = json.dumps(values) req = urllib2.Request(url, data, {‘Content-Type‘: ‘application/json-rpc‘}) res = urllib2.urlopen(req, data) output = json.loads(res.read()) return output def authenticate(url, username, password): values = {‘jsonrpc‘: ‘2.0‘, ‘method‘: ‘user.login‘, ‘params‘: { ‘user‘: username, ‘password‘: password }, ‘id‘: ‘0‘ } output = requestjson(url, values) return output[‘result‘] def gethosts(groupname, url, auth): host_list = {} values = {‘jsonrpc‘: ‘2.0‘, ‘method‘: ‘hostgroup.get‘, ‘params‘: { ‘output‘: ‘extend‘, ‘filter‘: {‘name‘: groupname}, ‘selectHosts‘: [‘host‘] }, ‘auth‘: auth, ‘id‘: ‘2‘ } output = requestjson(url, values) for host in output[‘result‘][0][‘hosts‘]: host_list[host[‘host‘]]=(host[‘hostid‘]) #return host_list hosts_sort = [] for host in sort_strings_with_emb_numbers2(host_list.keys()): hosts_sort.append(host_list[host]) return hosts_sort def getgraphs(host_list, name_list, url, auth, columns, graphtype=0, dynamic=0): if (graphtype == 0): selecttype = [‘graphid‘] select = ‘selectGraphs‘ if (graphtype == 1): selecttype = [‘itemid‘, ‘value_type‘] select = ‘selectItems‘ graphs = [] for host in host_list: values = ({‘jsonrpc‘: ‘2.0‘, ‘method‘: ‘graph.get‘, ‘params‘: { select: [selecttype, ‘name‘], ‘output‘: [‘graphid‘, ‘name‘], ‘hostids‘: host, ‘filter‘: {‘name‘: name_list}, ‘sortfield‘: ‘name‘ }, ‘auth‘: auth, ‘id‘: ‘3‘ }) output = requestjson(url, values) bb = sorted(output[‘result‘]) if (graphtype == 0): for i in bb: graphs.append(i[‘graphid‘]) if (graphtype == 1): for i in bb: if int(i[‘value_type‘]) in (0, 3): graphs.append(i[‘itemid‘]) graph_list = [] x = 0 y = 0 for graph in graphs: graph_list.append({ ‘resourcetype‘: graphtype, ‘resourceid‘: graph, ‘width‘: ‘230‘, ‘height‘: ‘100‘, ‘x‘: str(x), ‘y‘: str(y), ‘colspan‘: ‘1‘, ‘rowspan‘: ‘1‘, }) x += 1 if x == int(columns): x = 0 y += 1 return graph_list def screencreate(url, auth, screen_name, graphids, columns): columns = int(columns) if len(graphids) % columns == 0: vsize = len(graphids) / columns else: vsize = (len(graphids) / columns) + 1 values = {‘jsonrpc‘: ‘2.0‘, ‘method‘: ‘screen.create‘, ‘params‘: [{ ‘name‘: screen_name, ‘hsize‘: columns, ‘vsize‘: vsize, ‘screenitems‘: [] }], ‘auth‘: auth, ‘id‘: 2 } for i in graphids: values[‘params‘][0][‘screenitems‘].append(i) output = requestjson(url, values) def main(): url = ‘http://ip/api_jsonrpc.php‘ username = ‘admin‘ password = ‘xxxxxxxxx‘ auth = authenticate(url, username, password) host_list = gethosts(groupname, url, auth) graph_ids = getgraphs(host_list, graphname, url, auth, columns) screencreate(url, auth, screen_name, graph_ids, columns) if __name__ == ‘__main__‘: parser = argparse.ArgumentParser() parser.add_argument(‘-g‘, dest=‘groupname‘, nargs=‘+‘, metavar=‘groupname‘, type=str, help=‘which group you want to select‘) parser.add_argument(‘-G‘, dest=‘graphname‘, nargs=‘+‘, metavar=‘graphname‘, type=str, help=‘which graph you want to select‘) parser.add_argument(‘-c‘, dest=‘columns‘, metavar=‘columns‘, type=int, help=‘the screen columns‘) parser.add_argument(‘-n‘, dest=‘screen_name‘, metavar=‘screen_name‘, type=str, help=‘the screen name‘) args = parser.parse_args() groupname = args.groupname graphname = args.graphname columns = args.columns screen_name = args.screen_name main()
使用方法:
python create_screen.py -g hadoop -G ‘Network traffic on bond0‘ -c 4 -n ‘Hadoop bond0‘
-g 要显示zabbix的群组。
-G 要显示的zabbix图形。
-c 显示几列,注意要调整脚本里的:‘width‘: ,‘height‘: 参数来设置大小。
-n 在screen 里面显示的名称。
上面的命令的意思就是:把haddop组里面每个服务器的Network traffic on bond0图形,接每列4个图形的显示在Haddop bond0的screen里。
