Hi, Sematext SPM <http://sematext.com/spm> monitors both Solr and ZK and should be able to alert you if either of them have issues. It doesn't specifically watch for Solr<==>Solr or Solr<==>ZK errors, but I think problems on either side would manifest as changes in metrics for which you could set up either threshold-based or anomaly detection based alerts.
Furthermore, if you ship your logs to a log management solution like Logsene <http://sematext.com/logsene>, assuming Solr and/or ZK log errors about S-S or S-ZK communication, you'll be able to pick those up and alert on them, too. In short, very much doable.
