CMDB数据收集-更新中
一、机器整体信息收集
主要用到的命令：
ipmitool lan print #获取ipmi地址
hostname #获取主机名
dmidecode -t system #获取设备型号和sn等信息
import subprocess hostname = subprocess.Popen("hostname", stdout=subprocess.PIPE, shell=True).stdout.read().decode().split('\n')[0] IPMI = subprocess.Popen("ipmitool lan print | grep 'IP Address '| grep -v Source | awk -F ':' '{print $2}'", stdout=subprocess.PIPE, shell=True).stdout.read().decode().split('\n')[0] filter_keys = ['Manufacturer','Serial Number', 'Product Name', 'UUID', 'Wake-up Type'] for key in filter_keys: try: res = subprocess.Popen("dmidecode -t system | grep '%s'" % key, stdout=subprocess.PIPE, shell=True) result = res.stdout.read().decode data_list = result.split(':') if len(data_list) > 1: raw_data[key] = data_list[1].strip() else: raw_data[key] = '' except Exception as e: print(e) raw_data[key] = '' data = dict() data['Manufacturer'] = raw_data['Manufacturer'] data['sn'] = raw_data['Serial Number'] data['model'] = raw_data['Product Name'] data['uuid'] = raw_data['UUID'] data['wale_up_type'] = raw_data['Wake-up Type'] data['hostname'] = hostname data['IPMI'] = IPMI
二、操作系统信息收集
主要用到的命令：
lsb_release -a
def get_os_info(): destributor = subprocess.Popen("lsb_release -a | grep 'Distributor ID'", stdout=subprocess.PIPE, shell=True) destributor = destributor.stdout.read().decode().split(":") releas = subprocess.Popen("lsb_release -a | grep 'Description'", stdout=subprocess.PIPE, shell=True) releas.releas.stdout.read().decode().split(":") data_dice = { "os_destribution": destributor[1].strip() if len(destributor) > 1 else "", "os_release": release[1].strip() if len(release) > 1 else "", "os_type" : "linux" } return data_dict
三、cpu信息收集
实现方法：
cat /proc/cpuinfo
def get_cpu_info(): raw_cmd = 'cat /proc/cpuinfo' raw_data = { 'cpu_model': "%s |grep 'model name' |head -1 " % raw_cmd, 'cpu_count': "%s |grep 'processor'|wc -l " % raw_cmd, 'cpu_core_count': "%s |grep 'cpu cores' |awk -F: '{SUM +=$2} END {print SUM}'" % raw_cmd, } for key, cmd in raw_data.items(): try: result = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True) raw_data[key] = result.stdout.read().decode().strip() except ValueError as e: print(e) raw_data[key] = "" data = { "cpu_count": raw_data["cpu_count"], "cpu_core_count": raw_data["cpu_core_count"] } cpu_model = raw_data["cpu_model"].split(":") if len(cpu_model) > 1: data["cpu_model"] = cpu_model[1].strip() else: data["cpu_model"] = '' return data
四、内存信息收集
实现方法：
dmidecode -t memory
def get_ram_info(): raw_data = subprocess.Popen("dmidecode -t memory", stdout=subprocess.PIPE, shell=True) raw_list = raw_data.stdout.read().decode().split("\n") raw_ram_list = [] item_list = [] for line in raw_list: if line.startswith("Memory Device"): raw_ram_list.append(item_list) item_list = [] else: item_list.append(line.strip()) ram_list = [] for item in raw_ram_list: item_ram_size = 0 ram_item_to_dic = {} for i in item: data = i.split(":") if len(data) == 2: key, v = data if key == 'Size': if v.strip() != "No Module Installed": ram_item_to_dic['capacity'] = v.split()[0].strip() item_ram_size = round(v.split()[0]) else: ram_item_to_dic['capacity'] = 0 if key == 'Type': ram_item_to_dic['model'] = v.strip() if key == 'Manufacturer': ram_item_to_dic['manufacturer'] = v.strip() if key == 'Serial Number': ram_item_to_dic['sn'] = v.strip() if key == 'Asset Tag': ram_item_to_dic['asset_tag'] = v.strip() if key == 'Locator': ram_item_to_dic['slot'] = v.strip() if item_ram_size == 0: pass else: ram_list.append(ram_item_to_dic) raw_total_size = subprocess.Popen("cat /proc/meminfo|grep MemTotal ", stdout=subprocess.PIPE, shell=True) raw_total_size = raw_total_size.stdout.read().decode().split(":") p = {} ram_sizelist = [] for i in ram_list: info = i['capacity']+'@'+i['speed'] ram_sizelist.append(info) for i in ram_sizelist: if ram_sizelist.count(i)>0: p[i] = ram_sizelist.count(i) fres = '' for (k , v) in p.items(): fres += '%s*%d' % (str(k).replace('b','').replace(' ','').strip('\''),v)+'+' res=fres[:-1] ram_data = {'ram': ram_list} ram_data['ram_num'] = str(len(ram_list)) ram_data['ram_info'] = res if len(raw_total_size) == 2: total_gb_size = int(raw_total_size[1].split()[0]) / 1024**2 ram_data['ram_size'] = total_gb_size return ram_data
五、网卡信息收集
实现方法：
由于ifconfig在centos6和centos7上的返回结果不同，所以使用ip a的方式获取信息
def get_nic_info(): raw_data = subprocess.Popen("ip a | grep -E 'mtu|inet|ether' | grep -v inet6", stdout=subprocess.PIPE, shell=True) raw_list = raw_data.stdout.read().decode().split("\n") raw_ram_list = [] item_list = {} for line in raw_list: r = '^[0-9]' res = re.search(r, line) if not res: if str("ether") in line: mac = line.split("ether")[1].split()[0] item_list['mac'] = mac if str("inet") in line: ip = line.split("inet")[1].split()[0] ip_addr = ip.split("/")[0] netmask = ip.split("/")[1] item_list['ip_address'] = ip_addr item_list['net_mask'] = exchange_maskint(int(netmask)) else: item_list={} nic_name = line.split(":")[1].strip() item_list['name'] = nic_name item_list['module'] = 'unknow' item_list['mac'] = 'None' raw_ram_list.append(item_list) return {'nic':raw_ram_list} def exchange_maskint(mask_int): bin_arr = ['0' for i in range(32)] for i in range(mask_int): bin_arr[i] = '1' tmpmask = [''.join(bin_arr[i * 8;i * 8 + 8]) for i in range(4)] tmpmask = [str(int(tmpstr, 2)) for tmpstr in tmpmask] return '.'.join(tmpmask)
六、磁盘信息收集
这里用到python中的megacli模块
pip install megacli
from megacli import MegaCLI, MegaCLIError def get_disk_info(): cli=MegaCLI() disks = cli.physicaldrives() result = {'physicak_disk_driver':[]} for disk in disks: sn = disk['inquiry_data'].split() if 'seagate' in sn: manufacturer = 'seagate' pn = sn[1] sn = sn[2] elf 'intel' in sn: manufacturer = 'intel' pn = sn[2] sn = sn[0] elif 'mfaoaa70' in sn: manufacturer = 'hgst' pn = sn[2] sn = sn[0] elif 'sn05' in sn: manufacturer = 'sn05' if str('-') in sn[0] pn = sn[0].split('-')[1] sn = sn[0].split('-')[0] else: pn = 'None' sn = sn[0] elif 'sn04' in sn: manufacturer = 'sn04' if str('-') in sn[0] pn = sn[0].split('-')[1] sn = sn[0].split('-')[0] else: pn = 'None' sn = sn[0] elif 'sn02' in sn: manufacturer = 'sn02' if str('-') in sn[0] pn = sn[0].split('-')[1] sn = sn[0].split('-')[0] else: pn = 'None' sn = sn[0] elif 'hgst' in sn: manufacturer = 'hgst' pn = sn[1] sn = sn[2] elif 'hitachi' in sn: manufacturer = 'hitachi' pn = sn[1] sn = sn[2] elif 'wd' in sn: manufacturer = 'wd' pn = sn[1] sn = sn[2] elif 'toshiba' in sn: manufacturer = 'toshiba' pn = sn[1] sn = sn[2] else: manufacturer = 'None' pn = "None" sn = "None" disk_dict = {} disk_dict['model'] = pn disk_dict['sn'] = sn disk_dict['slot'] = str(disk['slot_number']) disk_dict['size'] = str(round(float(disk['raw_size'])/1024/1024/1024)) disk_dict['manufacturer'] = manufacturer disk_dict['pd_type'] = disk['pd_type'] if 'dirve_postion' in disk or 'drive_position' in disk: try: disk_dict['raid_group'] = disk['dirve_postion'].split()[0].split(",")[0] except Exception as e: disk_dict['raid_group'] = disk['dirve_position'].split()[0].split(",")[0] result['physical_disk_driver'].append(disk_dict) if result['physical_disk_driver'] == []: raw_data = subprocess.Popen("lshw -c disk -json -quiet | grep -v ^$" , stdout=subprocess.PIPE, shell=True) raw_str_old = str("[")+raw_data.stdout.read().decode().replace('\n','').strip()+str("]") raw_str=re.sub('} +{','},{',raw_str_old) raw_list=json.loads(raw_str) for line in raw_list: item_list = {} if str("product") in line.keys(): item_list['model'] = line["product"] elif str("serial") in line.keys(): item_list['sn'] = line["serial"] elif str("handle") in line.keys(): item_list['sn'] = line["handle"] if str("size") in line.keys(): item_list['size'] = str(int(line["size"]/1024/1024/1024))+str("GB") if str("description") in line.keys(): item_list['py_type'] = line["description"] if str("size") in line.keys(): result['physical_disk_driver'].append(item_list) p = {} disk_sizelist = [] for i in result['physical_disk_driver']: if 'py_type' in i.keys(): info = i['py_type']+'@'+i['size'] else: info = 'unknow@'i['size'] disk_sizelist.append(info) for i in disk_sizelist: if disk_sizelist.count(i)>0: p[i] = disk_sizelist.count(i) fres='' for (k,v) in p.items(): fres += '%s*%d' % (str(k),strip('\''),v)+'+' res=fres[:-1] result[diskinfo]=res return result
