Any reason you wanted to parse the year 1912. Right now the timestamp we have set is Uint instead of int https://github.com/SigNoz/signoz-otel-collector/blob/921457ce79766889fe472d0fbf35a[…]xporter/clickhouselogsexporter/migrations/000001_init_db.up.sql . Because of this I guess this issue is occurring.

thanks @nitya-signoz @Ankit Nayan i guess this means i can't predate UNIX epoch. i am not sure it'll be problematic. thank you for pointing it out.

just testing.

@nitya-signoz if i have current scenario where log items are missing in clickhouse, what would be a good place to start debugging ? i see that it has left the log collector's cluster but checking 
signoz_logs.logs
i do not see the log entry. on log source side:

on clickhouse, there are no new records:
Copy code
select body from signoz_logs.logs where log_file_path like '%echoer%' and trace_id != '' limit 10\G;

7 rows in set. Elapsed: 0.043 sec. Processed 2.98 million rows, 30.60 MB (69.01 million rows/s., 708.10 MB/s.)
any idea?
i see that it has left the log collector's cluster
or at least I think it does signify (the debug log) that it has left the source collector's cluster 😅
If I replay the log source (restart collector - it has start beginning set to true), it does reach clickhouse.

Interestingly, if anything fails to export then ideally it will be logged in the otel collector errors. Can’t think of a case right now but it will be helpful if you can share the configs, will get a better idea. Or if it’s for a specific kind of log, then we can try to reproduce with only that kind of log.

Interestingly, if anything fails to export then ideally it will be logged in the otel collector errors
yap. have not seen any errors in the otel log collectors.
i can try sniffing on the hops to 
10.248.19.100:4317
but i thought there might be a meta table in clickhouse to check if records ever made it. is there a compaction going on btw?
(if there is even such thing in clickhouse)
even if there is, i wouldn't know - clickhouse logs show it is chugging along rather well 😅
Or if it’s for a specific kind of log, then we can try to reproduce with only that kind of log.
here it is:
Copy code
kubectl run --namespace us -it --rm --restart=Never --image=alpine echoer -- \
  echo '{"level":"info","ts":"2022-09-01T11:12:36.901569069+1100","msg":"hello","error":"eeeeerrrrr","trace_id":"234a5bcd543ef3fa53ce929d0e0e4736","span_id":"b4b37b64bb3f6141"}'
n
The config files seem to be all good, And also here all your logs have the same timestamp as seen on the regex which won’t cause any issues. Also, how did you verify that some logs are missing? You can also use a log generator that we have for testing purposes https://github.com/SigNoz/flog we have used it here https://github.com/SigNoz/logs-benchmark/blob/5c1990d8637beee6326dbcb6f376ed268f540246/signoz/signoz-client/docker-compose.yaml#L18
Have tried to replicate this locally but seems all the logs are getting ingested for me. Tried using a script which generates logs with a counter to check ordering as well as missing values but all seems to be ingested correctly.
Copy code
package main

import (
	"fmt"
	"os"
	"time"

	log "<http://github.com/sirupsen/logrus|github.com/sirupsen/logrus>"
)

func main() {

	customFormatter := &log.JSONFormatter{}
	customFormatter.TimestampFormat = "Mon, 02 Jan 2006 15:04:05 MST"

	f, err := os.OpenFile("testlogrus.log", os.O_APPEND|os.O_CREATE|os.O_RDWR, 0666)
	if err != nil {
		fmt.Printf("error opening file: %v", err)
	}

	defer f.Close()

	log.SetOutput(f)

	log.SetFormatter(customFormatter)
	for {
		time.Sleep(10 * time.Millisecond)
		log.WithFields(
			log.Fields{
				"status": "hello",
				"name":   "xyz",
			},
		).Info("This is a log message : " + fmt.Sprint(i))
	}
}
