使用categraf的oracle模块配合夜莺提供的仪表盘有些页面是空白的如何处理？

[eguotangseng]

Relevant config.toml

[[metrics]]
mesurement = "sessions"
label_fields = [ "status", "type" ]
metric_fields = [ "value" ]
timeout = "3s"
request = '''
SELECT status, type, COUNT(*) as value FROM v$session GROUP BY status, type
'''
有仪表盘中oracle_sysmetric_buffer_cache_hit_ratio_value，这个页面的sql语言吗？
