zombodb 几个方便的_cat api

zombodb 暴露所有es _cat/ api 为视图，我们可以通过视图方便的查询es 的信息，默认在zdb的schema 中

包含的视图

几个方便的view

• 查看索引统计信息zdb.index_stats

select * from zdb.index_stats;
-[ RECORD 1 ]----+-------------------------------------------
alias | postgres.public.products.idxproducts-17176

• 查询es 集群文档信息 zdb.cat_count

• 查看索引信息 zdb.cat_indices

select * from zdb.cat_indices;
-[ RECORD 1 ]--+-------------------------------------------

pri | 5
rep | 0
docs.count | 5
docs.deleted | 0
store.size | 23297
pri.store.size | 23297

• es 集群节点属性信息zdb.cat_nodeattrs

-[ RECORD 1 ]---------------------
url | http://elasticsearch:9200/
node | YYRl4wX
host | 172.18.0.2
ip | 172.18.0.2
relo | 0
-[ RECORD 1 ]---------------------
url | http://elasticsearch:9200/
node | YYRl4wX

attr | ml.machine_memory
value | 2095869952
-[ RECORD 2 ]---------------------
url | http://elasticsearch:9200/
node | YYRl4wX
host | 172.18.0.2
ip | 172.18.0.2
attr | xpack.installed
value | true
-[ RECORD 3 ]---------------------
url | http://elasticsearch:9200/
node | YYRl4wX
host | 172.18.0.2
ip | 172.18.0.2

value | 20
-[ RECORD 4 ]---------------------
url | http://elasticsearch:9200/
node | YYRl4wX
host | 172.18.0.2
ip | 172.18.0.2
attr | ml.enabled
value | true

• es 集群节点拓扑查看zdb.cat_nodes

select * from zdb.cat_nodes;
url | http://elasticsearch:9200/
id | YYRl
pid | 1
ip | 172.18.0.2
port | 9300
http_address | 172.18.0.2:9200
version | 6.6.0
build | a9861f4
jdk | 11.0.1
disk.total | 62722478080
disk.used | 6214967296
disk.avail | 56507510784
disk.used_percent | 9.91
heap.current | 212820616
heap.percent | 41
heap.max | 518979584
ram.current | 2018529280
ram.percent | 96
ram.max | 2095869952
file_desc.current | 237
file_desc.percent | 0
file_desc.max | 1048576
cpu | 1
.....

说明

zombodb 暴露的视图还是比较多，同时对于es 的信息展示还是很全的
