2) 配置Aodh (1) 编写aodh配置文件 [root@node1 ~(keystone)]# mv /etc/aodh/aodh.conf /etc/aodh/aodh.conf.bak [root@node1 ~(keystone)]# vim /etc/aodh/aodh.conf [DEFAULT] log_dir = /var/log/aodh transport_url = rabbit://openstack:password@192.168.10.11

(2) 编写wsgi配置文件 [root@node1 ~(keystone)]# vim /etc/httpd/conf.d/20-aodh_wsgi.conf Listen 8042 <VirtualHost *:8042> DocumentRoot "/var/www/cgi-bin/aodh" <Directory "/var/www/cgi-bin/aodh"> AllowOverride None Require all granted </Directory>

3) SELinux及防火墙设定 [root@node1 ~(keystone)]# semanage port -a -t http_port_t -p tcp 8042
[root@node1 ~(keystone)]# firewall-cmd --add-port=8042/tcp --permanent success [root@node1 ~(keystone)]# firewall-cmd --reload success5.4 使用Aodh
2) 设定警告 # 设定名为cpu_hi的警告，当CPU大于50%时，发送警告 [snow@node1 ~(keystone)]$ openstack alarm create \ --name cpu_hi \ --type gnocchi_resources_threshold \ --description 'CPU High Average' \ --metric cpu_util \ --threshold 50.0 \ --comparison-operator gt \ --aggregation-method mean \ --granularity 300 \ --evaluation-periods 1 \ --resource-type instance \ --resource-id 0b95443b-58d2-41cd-bb34-2c6f81b5582f +---------------------------+--------------------------------------+ | Field | Value | +---------------------------+--------------------------------------+ | aggregation_method | mean | | alarm_actions | [] | | alarm_id | 5bf13f52-be47-41f6-9955-64e60fcbcc0d | | comparison_operator | gt | | description | CPU High Average | | enabled | True | | evaluation_periods | 1 | | granularity | 300 | | insufficient_data_actions | [] | | metric | cpu_util | | name | cpu_hi | | ok_actions | [] | | project_id | 7146a34d5b744320b2ed45af5b2e761b | | repeat_actions | False | | resource_id | 0b95443b-58d2-41cd-bb34-2c6f81b5582f | | resource_type | instance | | severity | low | | state | insufficient data | | state_reason | Not evaluated yet | | state_timestamp | 2020-02-07T13:35:29.904709 | | threshold | 50.0 | | time_constraints | [] | | timestamp | 2020-02-07T13:35:29.904709 | | type | gnocchi_resources_threshold | | user_id | 54f3ece13d6147928303ef4112e1f0e9 | +---------------------------+--------------------------------------+
