### Stack Traces ### Getting Stack Traces
A stack trace provides a very detailed look into the current state of the geth node. It helps us to debug issues easier as it contains information about what is currently done by the node. Stack traces can be created by running `debug.stacks()` in the Geth console. If the node was started without the console command or with a script in the background, the following command can be used to dump the stack trace into a file.
```
geth attach <path-to-geth.ipc> --exec "debug.stacks()" > stacktrace.txt
```
Geth logs the location of the IPC endpoint on startup. It is typically under `/home/user/.ethereum/geth.ipc` or `/tmp/geth.ipc`.
`debug.stacks()` also takes an optional `filter` argument. Passing a package name or filepath to `filter` restricts the output to stack traces involcing only that package/file. For example:
```sh
debug.stacks("enode")
```
returns data that looks like:
```terminal
