Graylog 2.2 update from 2.1: Error processing message RawMessage

ankit · February 20, 2017, 7:35am

I have a graylog cluster with one master and one node.
All was running fine until I updated to the latest version of graylog 2.2 from older 2.1.

Since the update, I am getting the following error in the graylog logs.

2017-02-20T11:09:49.983+05:30 ERROR [DecodingProcessor] Unable to decode raw message RawMessage{id=fefb57e0-f72e-11e6-a442-0050568c38ff, journalOffset=67018809, codec=syslog, payloadSize=128, timestamp=2017-02-20T05:39:49.982Z, remoteAddress=/10.1.15.80:65270} on input <58901f57b08e8d505ca0e93f>.

Please help me fix it.

Hej @ankit

please forgive me that I just edited your text a little (make the log more readable)

your issue might be related to: https://github.com/Graylog2/graylog2-server/pull/3503

We will release a bug fix within the next days that should fix this issue.

regards
Jan

ankit · February 23, 2017, 11:24am

Hi Jan,

I have upgraded the server to graylog-server-2.2.1-1 still the issue has not been resolved.

I will be grateful if you could confirm that the bug was fixed in the above mentioned release.

If yes, please guide me how to get rid of the error.

Thanks and Regards
Ankit Sharma

jan · February 23, 2017, 11:39am

as already written - my statement was just a first guess!

When I look again at your given error message that might be more a reason that your timestamp in your message is not parseable. You should check if your sendet messages are following Syslog RFC.

If not, you might want to switch to a Plain/Raw Input and parse all values with extractors or pipelines out of the message.

regards
Jan

ankit · February 24, 2017, 3:33am

Hi Jan,

Plain/Raw Input is an option, but I am unable to understand how it was working before the update to 2.2.

It was working fine in the version 2.1.

Nothing has been changed on the source side.

Only after the update was made to the version 2.2 it started throwing errors in the logs.

Nothing in any of the sources have changed.

Interestingly, the error is being thrown from Input Syslog UDP which in my configuration is receiving logs from Network Devices and Linux Servers.

Please advise if a downgrade to the version 2.1 is possible or if there is any other solution rather than going to plain text / raw msg.

Thanks and Regards
Ankit

jan · February 24, 2017, 1:41pm

Hej @ankit

downgrade is not possible.

Without any more information on how you ingest messages, what your architecture is looking the first statement was my first and only try to be a miracle. It looks like the issue, but it might be something that I do not know.

With kind regards
Jan

ankit · February 27, 2017, 6:27am

Hi Jan,

I have been looking deeper into the issue and after changing the input to Raw, I was able to get some idea of what the issue probably is.

The logs being received after the upgrade are unable to process the Sequence Number sent by the switches.

E.g.

<186>1541801: Feb 27 06:09:00.481: %HARDWARE-2-FAN_ERROR: Fan Failure

<186>1541800: Feb 27 06:08:59.485: %HARDWARE-2-FAN_ERROR: Fan Failure

<187>148094: Feb 27 06:07:29.716: %LINK-3-UPDOWN: Interface GigabitEthernet1/0/15, changed state to down

<189>148093: Feb 27 06:07:28.713: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/15, changed state to down

The error shown in the graylog logs is
Invalid format: “148093:” is malformed at “:”

This number is actually a Sequence Number which keeps on increasing by +1

The error shown in the graylog logs is
Invalid format: “148094:” is malformed at “:”

and so on…

This did not happen in the earlier version.

Could this parsing error be solved?

Thanks and Regards
Ankit Sharma

jan · February 27, 2017, 9:03am

Hej @ankit

looks like your message does not follow rfc3164 or rfc5414 and I can’t argue why this was handled by Graylog before the Update to 2.2.X

Maybe @jochen can jump in.

<189>148093: Feb 27 06:07:28.713: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet1/0/15, changed state to down

These aren’t valid syslog messages according to RC 3164 or RFC 5424.

Which syslog daemon or network appliances are generating these messages?

For now, I’d recommend using a Raw/Plaintext Input and some extractors to process these messages.

ankit · February 27, 2017, 9:22am

Dear jochen,

The messages are being generated by Cisco Layer 3 Switches and no configuration has been changed in the switches. It is only that after the upgrade was made error logs were generated.

I am still looking deeper into the logs of the switches as well for possible changes.

In the mean time, can you plz confirm that the update has not caused any such change.

Thanks for your help till now…

I will keep on updating you for the same.

Thanks and Regards
Ankit

Parsing Syslog messages has been made stricter in Graylog 2.2.0:

Problems parsing RFC3164 Syslog Messages with ISO8601 timestamps

opened 05:59PM - 14 Oct 16 UTC

closed 04:21PM - 21 Dec 16 UTC

jwood-krg

bug triaged

## Summary Graylog's SyslogCodec mishandles older RFC3164-style syslog messag…es that contain an ISO8601 timestamp. Example message that causes unwanted behavior: `<6>2016-10-12T14:10:18Z hostname testmsg[20]: {"cf_origin":"firehose","deployment":"cf","event_type":"ValueMetric","ip":"127.0.0.1","job_index":"0","level_mod":"6","msg":"","name":"RequestLatency","origin":"bbs","time":"2016-10-12T14:10:18Z","unit":"nanos","value":2.6071897e+07}"` ## Expected Behavior Section 5.1 of [RFC3164](https://www.ietf.org/rfc/rfc3164.txt) says that implementers may wish to use an ISO8601 timestamp, so the expected behavior is that this is parsed out properly. ## Current Behavior In SyslogCodec, messages of the above format match the regex on [L64](https://github.com/Graylog2/graylog2-server/blob/2.1.1/graylog2-server/src/main/java/org/graylog2/inputs/codecs/SyslogCodec.java#L64), which cause it to be parsed to RFC5424 standards. This causes a mangling of the fields, with the timestamp, application name, and process id becoming random words in the message part. ## Possible Solution On line 64 of [SyslogCodec](https://github.com/Graylog2/graylog2-server/blob/2.1.1/graylog2-server/src/main/java/org/graylog2/inputs/codecs/SyslogCodec.java#L64), change the regex from: `<\\d+>\\d.*` to: `<\\d{1,3}>[1-9]\\d{0,2}\\s.*` RFC5424 defines the syslog header to start with `<PRI>VER`, where PRI is a 1-3 digit number from 0-191, and VER is a 1-3 digit number from 1-999. Matching this will ensure that RFC3164 syslog messages with ISO8601 timestamps aren't interpreted as RFC5424 messages. This will also require a small update to syslog4j-graylog2 to prevent the timestamp from throwing a date parsing exception and getting replaced with Date(). I'll submit an issue to that project as well. ## Steps to Reproduce (for bugs) 1. Run Graylog 2.1.1 and set up a Syslog TCP stream 2. Save the above message to a file, let's call it testmsg 3. `cat testmsg|nc grayloghost port` 4. Check Graylog, find mangled fields in the message. ## Context This was discovered when trying to use Graylog to collect stats and other messages from Pivotal Cloud Foundry using the firehose-to-syslog nozzle provided to funnel stats into syslog messages. Due to the message content being JSON, the mangling of the message field causes the JSON extractor to fail on a large portion of messages. ## Your Environment - Graylog Version: 2.1.1 - Elasticsearch Version: 2.3.3 - MongoDB Version: 3.2.6 - Operating System: RHEL 7.2 - Browser version: Chrome 52

I am also experiencing this issue since upgrading from 2.1 -> 2.2. Was working fine for 9+ months.

Sending in to Syslog UDP from a Sophos UTM firewall and it stopped working. After some packet captures on the Graylog server (CentOS), I confirmed that the traffic was making it to the server, and I could see the packet rate in the Graylog UI.

Finally after checking graylog-server logs, I found similar errors which lead me here.

Are you sending messages from your Cisco devices directly to Graylog or are you aggregating them before?

The duplicated sequence number looks fishy.

Yes, the messages are directly from Cisco switches.

I seem to have ran in to this same issue - I had began testing with the 2.1 OVA, by the time I came around to doing my setup. 2.2.2 was out and I can’t seen messages to syslog UDP, can send Raw fine.

Any fix for this yet? I’m trying to send logs from a Cisco Meraki firewall MX100.

Yes, use a Raw/Plaintext UDP input instead of a Syslog UDP input and add some extractors or use the message processing pipeline to get structured information out of these messages.
