# 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"。
3. 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
   ```
   
4. 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。
   
5. 按"Esc"，然后执行":wq!"命令保存并退出。
