Heka Debugging
From time to time something went wrong with any software so there are a few words about debugging.
Save data to file
The easiest way to debug is to configure FileOutput and save all data in debug file.
To encode output is used RstEncoder
To enable such debugging it is necessary to add config file, e.g /etc/lma_collector/00_debug.toml
Attention: this configuration is dangerous because it will create I/O load. Please be careful with debugging on production!
[RstEncoder] [output_file] type = "FileOutput" message_matcher = "Fields[aggregator] == NIL" path = "/var/log/heka-debug.log" perm = "666" flush_count = 100 flush_operator = "OR" encoder = "RstEncoder"
Example of output:
tail -100 /var/log/heka-debug.log

Debug data filtering
To avoid I/O overload if is possible to filter messages. To filter data only from test_decoder and save it into the /var/log/heka-debug-test-decoder.log file is used the following configuration:
01_debug_test_decoder_data.toml [output_file] type = "FileOutput" message_matcher = "Type == 'test_decoder'" path = "/var/log/heka-debug-test-decoder.log" perm = "666" flush_count = 100 flush_operator = "OR" encoder = "RstEncoder"
Remark: depends on your current Heka configuration you may need to enable RstEncoder. In this example it is already enabled in 00_debug.toml file.

If Heka can't start
If Heka is not able to start it is possible to run it manually:
- Disable resorce in CRM
- Run crm resource command:
#crm resource
crm(live)resource# list
... <SKIP> ...
Clone Set: clone_lma_collector [lma_collector]
Started: [ node-6.domain.tld ]
- Stop lma_ollector resource:
#crm(live)resource# stop lma_collector
crm(live)resource# stop clone_lma_collector
- Check lma_collector resource status. It should be stopped.
#crm(live)resource# list
Clone Set: clone_lma_collector [lma_collector]
Stopped: [ node-6.domain.tld ]
Now it is safe to run Heka manually.
- Create screen session:
#screen
- In screeen section switch into heka user
#sudo -H -u heka /bin/bash
$hekad -config /etc/lma_collector/
2016/01/31 17:23:39 Error reading config: open /etc/lma_collector/01_debug_test_decoder_data.toml: permission denied
- As you can see in example above error is related to file permissions:
# ls -lsa /etc/lma_collector/01_debug_test_decoder_data.toml
4 -rwx------ 1 root root 199 Jan 31 17:06 /etc/lma_collector/01_debug_test_decoder_data.toml
- File is owned by root and can't be read by heka. To fix it it is nessesary to fix owner or permittions
#chown heka:heka /etc/lma_collector/01_debug_test_decoder_data.toml
- Start heka again:
$ hekad -config /etc/lma_collector/
