nightingale 前端无法读取指snmp指标数据，但可以显示自动提示

categraf部署在n9e主机中，在categraf中可以获取snmp数据，但在前端无法获取数据，promql也可以自动提示index，可以如何判断问题所在呢？

上下两张图的截图没有对应上，信息量不够
Categraf的配置文件，最好贴出来
下面查询不到数据的截图全面一点

配置文件如下：

interval = "10s" 

[mappings]
"udp://172.20.189.81:161" = {name = "AP08A36U81", region = "bj", role = "poe", floor = "8", u = "A36"}
省略一些主机

[[instances]]
agents = [
    "udp://172.20.189.81:161",
    ...
]

interval_times = 1

## config for each request.
timeout = "5s"
version = 2
community = "snmp"
agent_host_tag = "ip"
retries = 3
max_repetitions = 50

[[instances.table]]
oid = "IF-MIB::ifTable"
name = "interface"
index_as_tag = true

filters_expression = "A"

[[instances.table]]
# 此处是重复的instances.table，但是采集周期不同，所以是一个空表
name = "optical"
index_as_tag = true

[[instances.table.field]]
oid = "HUAWEI-ENTITY-EXTENT-MIB::hwEntityOpticalRxLowThreshold"
name = "hwEntityOpticalRxLowThreshold"

通过 -test，可以获取到数据：但前端没有数据：
