# 如何修改SAP监控指标的采集周期
1. 登录安装监控Agent的节点。
2. 执行以下命令，打开监控指标文件"metrics.ini"。 **vim /usr/local/sapmon/config/metrics.ini**
   ```
   [interval]
   # unit is minute 1,5,15
   database_version = 1
   service_quantity = 1
   database_ha_active = 1
   sr_active = 1
   threads = 1
   recent_data_backup = 5
   recent_savepoint = 1
   column_tables_used_memory = 15
   schema_used_memory = 15
   disk_data_files = 1
   disk_usage = 1
   service_memory = 1
   host_memory = 1
   sql_service = 1
   sql_top_time = 1
   sql_top_mem = 1
   connections_total = 1
   table_cs_top_mem = 15
   system_replication = 1
   system_replication_takeover = 1
   alerts = 1
   # FOR APPLICATION
   logged_in_users = 1
   application_version = 1
   instance_quantity = 1
   application_ha_active = 1
   abap_short_dumps = 1
   abap_short_dumps_5m = 5
   jobs = 1
   lock_entries_usage = 1
   extended_memory_utilization = 1
   heap_memory_utilization = 1
   work_processes = 1
   update_records = 1
   rfc_ping = 1
   failed_idocs = 1
   dialog_response_time = 1
   dialog_db_request_time = 1
   j2ee_running_process = 1
   j2ee_thread = 1
   j2ee_session = 1
   j2ee_websession = 1
   j2ee_ejbsession = 1
   j2ee_vm_heap_size = 1
   ```
   
3. 按"i"，修改监控指标组的采集周期。 示例如下：
   database_ha_active = 5

   同一个指标组的采集周期是统一控制的，采集周期的单位为分钟，采集周期可选值为1、5、15分钟。
   
4. 按"Esc"，然后执行":wq!"命令保存并退出。
