I am running ElasticStack 7.13.4 with Filebeat on Windows 10
I am ingesting several types of logs with Filebeat and wanted to put each of them into their own Index.
In filebeat I created an input as
```auto
#-------------------------------
# H00
- type: log
enabled: true
fields:
logext: H00
logtype: history
paths:
- C:\Log_file\History\*.H00
encoding : utf-16
#-------------------------------
```
Later I created an output
```auto
#-------------------------------
pipelines:
- pipeline: log_history_h00_pipeline
when.equals:
fields.logext: H00
indices:
- index: "log-history-H00-%{+yyyy.MM.dd}"
when.equals:
fields.logext: H00
#-------------------------------
```
Seemed to work, but eventually I get an error message
```auto
illegal_argument_exception: index.lifecycle.rollover_alias [log-history-h00] does not point to index [log-history-h00-2021.10.03]
```
Investagating, I added this
```auto
#-------------------------------
POST /_aliases
{
"actions": [
{
"add": {
"index": "log-history-h00-2021.10.03",
"alias": "log-history-h00",
"is_write_index": true
}
}
]
}
#-------------------------------
```
Which seemed to clear the issues until later I got this
```auto
illegal_argument_exception: index name [log-history-h00-2021.10.03] does not match pattern '^.*-\d+$'
```
Somewhere I must have made a wrong turn.
Can someone please help with this?
Thank you!
Michael

I might mention this is how I am creating the index template
```auto
PUT _index_template/log-history-h00
{
"index_patterns": ["log-history-h00*"],
"priority": 1,
"template": {
"settings": {
"number_of_shards": 1,
"index": {
"lifecycle": {
"name": "my-ilm-policy",
"rollover_alias": "log-history-h00"
}
}
}
}
}
```
